Tension Lever (TLF-N·TL-N)
Caution
Product Description
[Features]
· When the lever is pulled up, the meshing serrations are disengaged and the lever becomes free.
· The thread diameter is thick and the lever is long, so a large clamping force can be obtained with a small amount of force.
· Except for the ball, it is made entirely of steel or stainless steel, making it robust and strong.
· Main body materials are available in steel and stainless steel.
· Can be used in narrow spaces where the lever cannot rotate 360°.
· After tightening the screws, the lever can be moved to any position.
[Applications]
· Suitable for strong screw tightening and position adjustment parts such as slides and slotted holes

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°.)
