Gussets are the most common connector here at Framing Tech. They allow the fastening of two pieces of extrusion at a 90° angle without the need for machining. One of their features is an alignment tab that helps hold the position in the T-slot, and also prevents the gusset from rotating. The mounting holes for most of our gussets is slotted, which allows for some "wiggle-room" when adjusting your positioning. Common uses for gussets are for mounting table tops from underneath, fastening a machine frame to its base, installing a divider wall, as lift points for counterbalance systems and much more!
