L40 Locks

Check up to five results to perform an action.

The L40 lock has an overall length of 3.770" and a maximum width of 0.820". It is used in castings with wall thicknesses ranging from 1" to 3". The hole pattern for this lock can be drilled with a hand-held drill. A drill bushing is provided to allow pilot drilling of all holes to make drilling of the 1/2" diameter holes easier. Because of the aggressive design of LNS locks these L40 locks hold up extremely well, even under the cyclic stresses generated by punch presses and shears.
