The L30 lock is used mostly for industrial repairs. With an overall length of 2.818" and a maximum width of 0.609" it is large enough to be considered an industrial application. This size is intended for casting thicknesses of 3/8" to 1". A drill pilot bushing comes with the kit to make drilling easier. It allows you to pilot drill all of the holes to 3/16" prior to drilling the larger holes of the pattern.

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.
