The Quick Frame to 10 series transition tee is made of nylon and is used with a Quick Frame profile which has built-in ridges that bite into the fastener to create tension without the use of additional hardware. It is used to transition from a 1" x 1" T-slotted profile using only a soft-faced mallet to form light-duty yet sturdy builds. The Quick Frame to 10 series transition tee requires no additional hardware and no machining services. For information on the mounting hardware for 10 series profiles refer to the "Suggested Hardware" tab.
