This is a elbow hinge piece of MicroRAX product used as a bracket to allow beams to pivot on the edge or use in a building system to build science, engineering, or advanced hobby and DIY projects.

The elbow hinge allows beams to pivot on the edge of the profile with about 180 degrees of rotation. In other words, at fully-closed the two beams will be parallel to each other. The bushing that connects the joint works with a 3mm OD shaft if you want to run a shaft through several joints. 

We are selling these as single joints so you'll need two of these to make a full elbow (one per side).

Features:

• +/- 180 degrees of rotation
• Bushing works with 3mm OD shafting
• Need 2 to build a complete elbow
