The RJ-20A's saddle is a \u003cstrong\u003edouble-screw design\u003c\/strong\u003e, so the pad can be set flat against a chassis rail that is not flat — which, on a full-size truck, is most of them — and the \u003cstrong\u003e3″ and 6″ extension adapters are in the crate as standard\u003c\/strong\u003e rather than sold on afterwards, so it reaches up into a high frame the day it arrives.\u003c\/p\u003e \u003cp\u003eIt is driven by \u003cstrong\u003eshop air\u003c\/strong\u003e, not electricity: there is no circuit to run, only a line to reach. And it is a heavy-duty jack in the literal sense — 20,000 lbs of capacity, a reinforced scissor structure and an oversized hydraulic cylinder.\u003c\/p\u003e \u003ch3\u003eWill It Fit?\u003c\/h3\u003e \u003cp\u003eA rolling jack is bought for a lift you already own, so the fitment questions are about your lift rather than your building. Measure before ordering - the measuring is the buyer's responsibility.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eRunway spacing — the figures here are contested.\u003c\/strong\u003e This page lists a support base adjusting from 47 7\/16″ to 63 3\/16″, and the manufacturer publishes a narrower band at both ends. Measure between the inside faces of your runways where the jack will actually sit, not at the ramp end, and then check that measurement with us.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eJack width.\u003c\/strong\u003e 25 1\/2″ overall - the space it occupies between the runways when it is parked out of the way.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eClearance underneath.\u003c\/strong\u003e The jack stands 14 9\/16″ at its lowest. That is the height it needs to roll into position beneath the vehicle, so it is the figure to check against the lowest thing your four-post will be carrying.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eReach — also contested.\u003c\/strong\u003e This page lists an arm-pad span of 45 1\/4″ to 72 5\/8″; the manufacturer publishes a shorter maximum reach. Reach is what lets the pads meet lift points on a small car and on a full-size truck without repositioning, so settle it before you order rather than after.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAir.\u003c\/strong\u003e The pump is pneumatic-hydraulic and runs at 0.8Mpa. There is no electrical connection to make, but a compressed air line has to reach the lift, and that is worth arranging before the jack arrives rather than after.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eFit is decided by your runways, not by the capacity badge\u003c\/h3\u003e \u003cp\u003eRolling jacks are frequently sold as though any jack fits any four-post. They do not. A fixed-width jack is built for one runway spacing, and if your lift is wider or narrower than the one it was designed around, it either will not seat or seats badly with the load in the wrong place. The extendable lower sliding assembly on the RJ-20A is strengthened and thickened so that it holds the jack steadily between the runways across its adjustment range, not merely so that it reaches.\u003c\/p\u003e \u003cp\u003eThat is also why it is worth buying a jack rated well above the axle load you expect. A 20,000 lb rating is not about lifting twenty thousand pounds. It is about what the frame is doing when you lift eight thousand, off-centre, on one corner, for the four hundredth time.\u003c\/p\u003e \u003ch3\u003eThe saddle, and why the pad is a two-screw design\u003c\/h3\u003e \u003cp\u003eThe frame saddle pad assembly uses a double-screwing design. Two independently adjusted screws let the pad sit flat against a chassis that is not flat, which on a full-size truck or a heavy-duty vehicle is most of them. A single-screw or fixed saddle contacts a sloped frame rail on an edge instead of a face, and edge contact under twenty thousand pounds of rating is exactly how frames get dented and pads get squeezed out sideways. The 3″ and 6″ extension adapters stack onto that saddle to reach up into a high chassis - included as standard, which is not universal in this category and is worth checking when you compare.\u003c\/p\u003e \u003ch3\u003eRollers, arms and the handle nobody mentions\u003c\/h3\u003e \u003cp\u003eThe rollers use a patented floating design in hardened stainless steel, zinc plated. A rolling jack spends its life dragged along gritty steel runways, and the rollers are what wear out first on a cheap one.\u003c\/p\u003e \u003cp\u003eThe guardrail doubles as a booster handle: something to push against when shifting a heavy jack along a runway, and a shield that keeps the oil hose from being trodden on. The kind of detail you notice only when it is absent.\u003c\/p\u003e \u003ch3\u003ePerfect For\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eHeavy-duty and full-size truck work\u003c\/strong\u003e on a four-post - the case the capacity and the saddle design were built around.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eCommercial service bays\u003c\/strong\u003e that need wheels-free work on a lift bought for drive-on convenience.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFleet operations\u003c\/strong\u003e, where brake and suspension work on the same vehicles happens week after week.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eShops with mixed runway spacings\u003c\/strong\u003e across more than one four-post, thanks to the adjustable base.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhat is in the crate\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eThe rolling jack with reinforced scissor structure and oversized hydraulic cylinder\u003c\/li\u003e \u003cli\u003ePneumatic hydraulic pump\u003c\/li\u003e \u003cli\u003eDouble-screwing frame saddle pad assembly, fitted as standard\u003c\/li\u003e \u003cli\u003e3″ and 6″ extension adapters, included as standard accessories\u003c\/li\u003e \u003cli\u003eExtendable lower sliding assembly and the ergonomic guardrail booster handle\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eNot supplied: the compressed air line and its fittings are yours to provide.\u003c\/p\u003e \u003ch3\u003eSpecifications\u003c\/h3\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth\u003eLifting capacity\u003c\/th\u003e \u003ctd\u003e20,000 lbs\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eLifting height, without adapters \u003cem\u003e(this page — contested)\u003c\/em\u003e \u003c\/th\u003e \u003ctd\u003e30 11\/16″ to 33 1\/2″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eLifting height, with adapters \u003cem\u003e(this page — contested)\u003c\/em\u003e \u003c\/th\u003e \u003ctd\u003e39 3\/4″ to 42 1\/2″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eMinimum height\u003c\/th\u003e \u003ctd\u003e14 9\/16″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eMinimum rubber pad height\u003c\/th\u003e \u003ctd\u003e16 3\/4″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eLifting time \u003cem\u003e(this page — contested)\u003c\/em\u003e \u003c\/th\u003e \u003ctd\u003eAbout 84 seconds\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth\u003eSupport base width \u003cem\u003e(this page — contested)\u003c\/em\u003e \u003c\/th\u003e \u003ctd\u003e47 7\/16″ to 63 3\/16″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eArm pads reach \u003cem\u003e(this page — contested)\u003c\/em\u003e \u003c\/th\u003e \u003ctd\u003e45 1\/4″ to 72 5\/8″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eOverall width\u003c\/th\u003e \u003ctd\u003e25 1\/2″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eExtension adapters\u003c\/th\u003e \u003ctd\u003e3″ and 6″, standard\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth\u003ePump\u003c\/th\u003e \u003ctd\u003ePneumatic\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eAir pressure\u003c\/th\u003e \u003ctd\u003e0.8Mpa\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ch3\u003eMeasure your runways, then check the spans with us\u003c\/h3\u003e \u003cp\u003e\u003cstrong\u003eMeasure your own four-post and confirm the support-base and arm-reach spans with us in writing before you order.\u003c\/strong\u003e The fit figures printed on this page are ones the manufacturer's current published specification disagrees with. Set against ours it gives a narrower support-base range at both ends, a shorter maximum arm-pad reach, a lower maximum lifting height both with and without the adapters, and a much shorter lifting time. On a rolling jack the first two are the whole purchase: they are what has to straddle the runways of a lift you already own, and a jack that cannot span them is scrap in a crate.\u003c\/p\u003e \u003cp\u003eWe assert neither set of figures. Ours have been republished by other sellers of this jack word for word, so numbers agreeing across the internet says nothing about which sheet is current — and printing a second set here would only leave you choosing between two. Send us the make of your four-post and the measurement between the inside faces of its runways. We will get the answer from the manufacturer and put it in writing before you commit.\u003c\/p\u003e \u003ch3\u003eCertification, stated plainly\u003c\/h3\u003e \u003cp\u003eThe product data we hold for the RJ-20A states no third-party safety certification or listing of any kind, and we will not imply one by decorating the page with badges. That is not the same as saying none exists - it means we have not seen it. If your insurer, your fleet policy or your local code requires a specific listing on lifting equipment, tell us before you order and we will put the question to the manufacturer in writing. For many shops it never comes up; when it does, a vague answer is worse than none.\u003c\/p\u003e \u003ch3\u003eShipping and delivery\u003c\/h3\u003e \u003cp\u003eThe RJ-20A ships by freight truck within the lower 48, quoted live against your address at checkout rather than estimated. A rolling jack is compact and extremely dense - much heavier than it looks, which catches people out. Unloading is the receiver's responsibility, so plan for a forklift rated for the crate or book a collection from the carrier's terminal, which already has the equipment and a dock. Residential delivery carries a residential fee, applied at checkout.\u003c\/p\u003e \u003cp\u003eInspect the crate before signing. Check the saddle and arms for bending, the scissor structure and hose for damage or weeping oil, and confirm both extension adapters are in the box; write anything you find on the bill of lading with the driver still there, and photograph it. Sign clean and the carrier holds proof the shipment arrived intact.\u003c\/p\u003e \u003ch3\u003eWarranty\u003c\/h3\u003e \u003cp\u003eThe product data for the RJ-20A does not publish a warranty term, so we will not print one. Ask us before you buy and we will send you the manufacturer's current written terms as they apply to your order. Our own claims process is set out at \u003ca href=\"https:\/\/mechanicsuperstore.com\/pages\/warranty-claims\"\u003emechanicsuperstore.com\/pages\/warranty-claims\u003c\/a\u003e.\u003c\/p\u003e \u003cp\u003eOne warning applies to every hydraulic jack: if something fails, do not take apart the pump, the cylinder or the saddle assembly before a claim is opened.
