C. Sherman Johnson Lever Arm Rigging Crimper Tool

The C. Sherman Johnson Lever Arm Rigging Crimper Tool is built specifically for Johnson hand-crimp terminals rather than general-purpose soft-metal sleeves. Its jaw geometry uses the width and relief pattern required by the manufacturer’s stainless hand-crimp fittings. That dedicated tooling matters because the integrity of a hand-crimped lifeline or rigging terminal depends on the fitting being formed correctly. Using unrelated crimping tools or non-Johnson fittings with this tool can produce an unsafe terminal and should be avoided.

The lever-arm design provides the mechanical advantage needed to form stainless fittings that require more force than soft copper or aluminum sleeves. The tool has two crimp cavities sized for 1/8 in and 3/16 in Johnson hand-crimp fittings. It is intended as a productive bench or shop tool for dealers and owners who perform repeated installations rather than a substitute for casual plier-style crimpers. The manufacturer specifically distinguishes its use from Nicropress-style tools developed for softer sleeve materials.

• Two dedicated crimp cavities for 1/8 in and 3/16 in fittings
• Lever-arm design develops force for stainless hand-crimp terminals
• Jaw relief pattern is specific to Johnson hand-crimp fittings
• Suited to repeated dealer or service-shop rigging work

Follow the fitting manufacturer’s crimp sequence and inspection instructions for every terminal made with this tool. Do not mix incompatible tooling and terminal systems, since a crimp can look complete while still failing to develop the intended holding strength.
