Use this Double Tee Nut to connect V-Slot and most T-Slot Extrusions end to end or use it on any connection point that has 20mm spacing
You can use these double tee nuts just like you would a standard tee nut to make any connection that you need.
Double tee nuts are compatible with any 5mm screws or attach the double tee nut with 2 5mm set screws (not included) to allow for a nice low profile solution that will let the OpenBuilds Wheels transition from one extrusion to the next.
