The Single Spring Unit
6 1/4" (158.8 mm) shut height units are recommended where maximum shut height is not great enough to accommodate the features available in the double and triple spring units.Maximum punch size is 1/4"(6.4 mm).

The Double Spring Unit
7 1/2" (190.5 mm) shut height unit is recommended for most applications for piercing up to a 5/16"(7.9 mm) diameter hole.

The Triple Spring Unit
7 1/2" (190.5 mm) shut height unit offers still greater stripping forces and is recommended for "tough" applications-where the units are stacked up against one another.This unit will pierce up to 5/16" (7.9 mm) diameter holes.

Several different dies are available.Selection of the die depends on the application and can have an economical advantage.These dies can also be "shimmed up" after excessive sharpening for still a greater savings.Shimming permits constant die height that eliminates material distortion resulting from punching with irregular die heights.Dies are easily removable for sharpening or replacement.

Adjustable Base Units have 1 1/2"(38.1 mm) adjustment[ 3/4 "(19 mm) each side of centerline] for punching staggered hole patterns.

These units can also be altered for special applications.
