✅ Forty millimeter lever provides comfortable hand operation
✅ Thirty one millimeter thread depth locks firmly into metal bases

💡 What causes premature failure in spring loaded mounting bolts during high torque operations?
These units stay handy and reliable when you skip the guesswork and lock in proper maintenance habits.
- Wipe down the housing to stop dust from grinding into the return spring
- Seat the shaft fully into tapped holes to eliminate play under side load
- Run a drop of synthetic grease on the guide rail so adjustments stay buttery smooth
