Works great
Size: 37" - 61"
Replaced a non USA made spindle jack thought was holding only the stairs and landing but was also supporting part of the house. The old one was rusting away/ fell apart when removed and was under sized from a big box store. This support is a Cadillac, sturdy and easy to adjust with the screw. Well worth the money spent. ... show more

These jack stands are the bomb! Easy to use. Th telescopic feature allows you to lift to any height. I used these to level out my 42 ft RV. It was soo easy. I did buy a hydraulic jack lift to lift the RV and then placed the jack’s appropriately.

Poor performance appeared used
Size: 13" - 17"
Product appeared used and the quality of the parts did not seem substantial for price paid also cost to ship. I retuned both items purchased and my refund was severely delayed which was not acceptable to me. I would not buy this product again.
