The Safe Jack Kit, No. 37M-BJRK-6W, offers bottle jack accessories, which help make standard bottle jacks safer to use and gives options that have never been available before, according to the company. The kit couples a hydraulic bottle jack with stackable and telescoping steel extensions to give a standard 6-ton bottle jack a lift range of 8" to 36". Interchangeable jack pads attach to the top of the extensions to grab the load which adds stability and prevents slipping. The kit includes one each: stackable 3”, 6” adjustable 8 to 12” extensions, one flat and one universal/round jack pad, 6-ton bottle jack and tool bag.
