Tension Lever (TLF-N·TL-N)

Caution
Product Description
In this type of lever handle, when the lever is pulled, the serrations engaged with each other are disengaged. Large clamping force can be obtained because the lever part is long.
[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 parts are made from stainless steel, so it is robust and strong

Usage Example

When you pull up the lever, the serrations on the thread section and the lever will come off.

Only the lever becomes free, so it can be turned to the desired position.

When you release your hand, the force of the built-in spring returns the lever so that it can apply clamping force.
(For 24 teeth, serrations are engaged every 15°, formula 360°/24 = 15°.)
