I wanted a remote holder that would attach to my Bed Frame post without having to screw it in and damage the wood of the frame. So I came up with this strap and brace approach. The strap is an open ended rectangle that you slip around the post. The strap has enough pressure not to slip down the post. Regardless my bed frame has iron work which it can sit on as well. The remote holder slots into the strap brace enclosing the post. This works with bed posts the size of 3 7/8 x 3 7/8 (98.36mmx103mm) but you can scale whole design appropriately.
