L20 Locks

Check up to five results to perform an action.

The L20 lock offers a considerable amount of strength for its size. Drilling the hole pattern is fast and easy. Because of its short length, it is very easy to locate installation sites on the casting. While it is often placed in larger castings in the automotive industry, it has many applications in industrial use. Use this lock in castings with a wall thickness of 0.375" to 0.750".
