I purchased these mounts to hang a pair of ~20lb. ea bookshelf speakers on my ceiling to use for an ATMOS setup in my home theater. I appreciate they are overbuilt, with a steel safety strap, and solid hardware included in the kit. When you're planning to mount something heavy and blunt at or above head height, you want to be confident that the thing isn't going to come crashing down on you. Very happy with these, would buy again.
