Review on A ABIGAIL Universal Floor Jack Rubber Pad Adapter: Pinch Weld Side Rail Protector Puck/Pad by Darrell Beecher

This washer is designed to be installed on the floor jack lift deck to mate with the weld flange on most one piece vehicles (factory jack location). I bought this to prevent paint damage on my 2020 Camry. I have a 2.5 ton, Chinese made, 25 year old ground hoe with a concave lifting bag/cup. The flange on my Camry actually damaged the washer the first time I used it. I solved the problem by filling the concave part of the lifting bag/cup with a clay cat which filled the empty space under the rubber disk and allowed me to lift the disk. Car without window deformation. I can try to fill the cavity at the bottom of the jack disc to prevent deformation but be aware that this product is hollow rather than solid and will deform if your jack has a concave jack cup/pad. I think the washer is more likely to deform even if there is a flat surface underneath as it has no structural integrity itself. I should have just put a V notch on a hockey puck instead of buying this item.
