Review: A must have for ram mounts - Works great for securing ram mounts. I ordered 4. Definitely cheaper than replacing ram mounts.
Review: Make sure you use the included washer! - These are great. As good or better than RAM. One warning: if you use the original RAM twist knob’s washer, this won’t lock. You MUST use the included washer which is a slightly different size. 10/10 product.

*by K***5 on May 19, 2026*

Looks to be decent build and looks nice. But can't use it as it came with no threads, so I'll have to tap it or return it
