THE DOUBLE SLIDE-IN ECONOMY T-NUT IS A FASTENING OPTION THAT SAVES TIME AND SIMPLIFIES THE ASSEMBLY PROCESS. IT LOADS FROM THE PROFILE ENDS AND IS AVAILABLE WITH OPTIONS IN SIZE AND FINISH. THE PILOT PROJECTION ADDS ADDITIONAL THREADING FOR INCREASED STRENGTH. THERE IS ALSO A TRIPLE SLIDE-IN ECONOMY T-NUT AVAILABLE. TIP: POSITION THE PILOT PROJECTION DOWN IN THE T-SLOT TO AVOID AN UNEVEN CONNECTION OR CRASHING.
