Worked great in a 2-post lift
Used 12 of these in a 2-post lift install. These things are awesome and very robust. Installed all 12 without a problem. Torqued all to 150ft lbs. after 1 week, I retorqued them all and all but 1 retorqued to 150ft lbs with less than 1/2 turn. One pulled almost all the way out. So, I hammered it back through and installed a new one and it torqued with less travel than the failed one. Faulty anchor? Faulty concrete? All good now.

⭐⭐⭐⭐⭐ Strong, reliable anchors — perfect for garage lifts
Used these CONFAST 7/8" x 6" wedge anchors to replace the floor anchors on my car lift, and they worked perfectly. Installation was straightforward, they hold tight, and the zinc plating gives good corrosion resistance. Solid build and exactly what you need to keep heavy equipment secure. If you’re mounting a lift, shelving, or anything heavy to concrete, these anchors get the job done safely and reliably.

They did the job and were a great price compared to others. I had some that bit hard and torqued down nicely. Others that took a while to bite and get a decent torque. Used to set up my 2 post hoist. End of the day they held down the hoist when lifting a 9000lb truck.
