Gussets are used to connect pieces of metal that may not have been possible beforehand. Not only that, but they also serve as a great way to strengthen your robot's joints.
VEX EDR gussets come in a variety of shapes and angles, to ensure that your robot will be as structurally sound as possible when it hits the competition floor.
Use these C-Channel Couplers to attach two VEX EDR 1x2x1 C-Channels together in line to make longer structural pieces.
To install this gusset, simply insert it between the two pieces of C-Channel you are wanting to join as shown in the image to the right, and bolt together as normal.
