  • 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
