6 Ton Extension Screw Collar
Adds 1.5 inches of stroke to a 6 ton bottle jack by extending the screw without increasing the starting height when used with a jack pad or jack extension. The size is perfect for most 6 ton bottle jacks with rams ranging from 1.25 -- 1.3 inches in diameter and screw diameters up to .955 inches
Extension screw collars provide the proper fit for jack extensions and jack pads but they also give the operator 100% of the usable stroke of the jack. The collars are easy to install taking only a few seconds and they can be removed just as easily.
These are standard equipment for our bottle jack recovery kits and should be used anytime extensions or jack pads are used for proper fit and to maximize the useful stroke of the jack.
Perfect/safe/compact addition to my current jack setup. Raises my lifted E350 Sportsmobile with ease. Could use less reminders regarding submitting an on line review.
Fits perfectly. Haven't used it yet
The extra inch and a half of lift is just what I needed in one of my applications.
Easy to use, well made item.
Used accessories yesterday and all went well. Great products.
I lost my collar adapter on a recovery. They are an excellent item. I bought a replacement and backup. You can’t beat safe jacks when you need to lift your rig in a tight spot. Safer that a scissor jack or high lift. Takes up little cargo space. I used similar products from the same company when I was on active duty with the US Army.
