The Katool KT-RJ50 Rolling Jack is designed as the perfect companion accessory for your KT-4H110 Four-Post Lift, significantly enhancing its functionality by providing reliable mid-lift access. This compact and low-profile scissor jack boasts a substantial 5,000-lb (approximately 2,268 kg) lifting capacity, making it ideal for a variety of undercarriage work and wheel service tasks on sedans, SUVs, and light trucks when used with compatible four-post lifts.
Engineered for optimal performance and durability in demanding shop environments, the KT-RJ50 features an efficient air/hydraulic operation mechanism, requiring an external air supply for power. Its scissor-style design ensures precise and level lifting, providing stable support for vehicles. The entire unit is protected by a durable powder-coated finish, which offers excellent resistance against corrosion and wear, ensuring long-lasting performance.
The low-profile design of the rolling jack allows for better clearance and maneuverability under lifted vehicles, while its smooth rolling action facilitates easy positioning along the runways of the four-post lift. This accessory is essential for shops looking to expand their service capabilities without investing in additional full-sized lifts.

The lift itself seems solid and works well now that it’s assembled. But the installation was a nightmare — poor instructions, some bolt holes didn’t align perfectly, and I had to fabricate a couple of spacers. If you’re handy, you can make it work.
Betty Collins –
I was nervous spending this much on a home garage lift, but this thing is built like a tank. The anti-slip runway surface gives me confidence and the caster kit makes it easy to reposition. Already done three oil changes and a brake job with it.
Betty Brooks –
This four-post lift is exactly what my garage needed. Installation took about a weekend with a buddy helping, but the end result is fantastic. Locks engage smoothly at every position and the lift feels incredibly stable. My truck sits up there like it’s on solid ground.
Betty Allen –
Went from a cluttered single-car garage to a fully functional two-car setup thanks to this lift. Park one car on top, work on another below. The installation guide could be better, but the product itself is outstanding.
Betty Smith –
Installed this in my 2-car garage and it transformed my workspace. The runways are wide enough for my full-size truck and the lifting speed is smooth and consistent. Safety locks click in positively. This is professional-grade equipment at a fair price.
John Edwards –
I run a small side business doing maintenance for friends and family. This lift handles everything from sedans to light trucks without breaking a sweat. The powder coat finish still looks new after months of use.
Anna Hill –
Overall a very solid four-post lift. Build quality is great and it feels very safe. Only reason for 4 stars is the instructions could be much better — had to figure out a few steps on my own. But the lift itself is excellent.
Jonathan Bailey –
After months of research, I pulled the trigger on this lift and couldn’t be happier. The build quality is top-notch — heavy gauge steel, clean welds, and a powder coat that looks like it’ll last. Raised my SUV for the first time and had zero concerns about stability.
Benjamin Rodriguez –
Bought this primarily for double parking in my garage but ended up using it for service work too. The clearance underneath is great and the approach ramps make driving on easy. My wife can even load her car up without issues.
Mark King –
The lift is excellent quality and works great. However, the installation manual is poorly translated and some diagrams are hard to follow. YouTube helped fill in the gaps. Product itself deserves 5 stars.
Jonathan Diaz –
Really like this lift overall. Sturdy, safe, and well-built. The only thing keeping it from 5 stars is the hydraulic fluid wasn’t included and the manual didn’t specify the type clearly. Minor issue for an otherwise great product.
Catherine Hall –
Compared this to lifts costing twice as much at my buddy’s shop and honestly can’t tell the difference in build quality. Everything about this lift screams durability. The approach ramps, drip trays, and caster kit being included is a nice bonus.
Joshua Lopez –
The lift itself is fantastic — heavy duty, smooth operation, great safety features. But assembly was a real project. Plan for a full weekend with help. Once it’s up, though, it’s perfect.
Patrick Phillips –
Great build quality and solid performance. The approach ramps could be a little longer for low-clearance vehicles, but otherwise this is an outstanding lift for the price.
Jacob Diaz –
As a retired mechanic, I know quality when I see it. This lift meets commercial standards in terms of build quality and safety features. The welds are clean, the hardware is grade 8, and the hydraulic system is properly engineered.
