Adjustable metal steel joists for reinforcing subfloors, floor joists, and beams. Thank you for viewing. I used these to reinforce the subfloor of my parents' house, but some were used as temporary supports, and the rest are leftover. I think some can also be used to reinforce beds. The items in the photos are all that are included. Please feel free to comment if you have any questions. I believe I purchased these at a nearby home improvement store. To keep shipping costs down, I will disassemble the parts before sending them. Please be aware of this.
