The 8839 is a spring-loaded, pop-out T-handle, manufactured by Camlock. This product features a sturdy body size very much alike with the 8835 but allows a range of locking inserts. It includes other NAMA dimensional standards.
This is equipped with 38mm flat cam, 1/4 or 1/2 turn operation. The handle rotates 90 ° or 180 ° when it is unlocked.
The front of the T-handle is textured for scratch resistance. When the cam is fitted to the T-handle, the tail nut is tightened with a force of 20-25 Nm.
