Constructed of 6061-T6 aluminum, this adaptor is extremely rigid and strong. It has (4) 6-32 thru holes. When used with 6-32 machine screws and Nyloc Nuts that aren’t tightened all the way, these beam adaptors are able to provide a rigid, yet movable joint.
For a solid structure that isn’t movable, simply tighten the nylock nuts completely. This adaptor is great for joining beams to great complex structures!
