Safety Tension Lever (STF-N, ST-N)

Normally, when the lever part is in the free state, pressing the lever pushes the serration into mesh and operation is possible. It is possible to prevent contact malfunction after tightening.

[Features]
· Large clamping force can be reached with lesser force since the thread diameter is thick and the lever is long.
· Besides the door knob, all is made from stainless steel, so it is robust and strong.
· In the push lock type, where the gear is used by pressing the lever, when the hand is released, the built-in spring allows the lever to return to its original position and rotate freely again, and it is safe from any incorrect handling
