MS3191

• Cycle Controlled Ratchet
• No dial adjustments required
• Available in 4 or 8 indent

The MS3191 still continues to set a standard of excellence for crimping tools. This series of crimping tools continues to be one of the easiest to use. Simply selecting the proper positioner determines the crimp depth, crimp location and point of ratchet release.

The four or eight indent crimp provides a uniform displacement of wire and contact material, on contact sizes 12-20 and wire sizes 12-26 AWG.

As with all Astro pin and socket crimp tools the MS3191 can be ordered with a variety of indentor configurations, including octadent (tool part number: 612600).

A large selection of positioners are available for this tool. Astro will custom design and manufacture positioners for you own special needs. Various tool-positioner combination packages are available. Extra positioners are conveniently stored in the tool handle. (See chart for details).

A gage kit (part number ATK 6000 [MS3196-2]) is available for the periodic gaging that is recommended.

This tool weighs approximately 20 ounces and is 9 ½ inches long.
