Jiffy-Tap

Extended Stroke:

Occasionally, you may need a longer tapping stroke than the standard Jiffy-Tap unit can provide. The extended stroke unit provides an additional 1 inch of usable stroke. The unit length is only increased by approximately 2 1/2 inches.

When ordering additional lead screws, they must be ordered with the extended stroke option also.
