The Proskit CP-5S2D is a crimp head attachment for the CP-371, CP-336F, and 1PK-3003F crimping frames, purpose-built for MC4 solar connector crimping. It is manufactured using a dewaxing casting process, which produces accurate dimensions and a consistent head profile critical for reliable MC4 contacts.

The head material is AISI 4140 alloy steel — a hardened grade that maintains its shape through high-volume crimping cycles. The CP-5S2D is supplied as a single unit, enabling it to be added to an existing frame or used as a replacement head.

Key Features

• Purpose-built for precision crimping of MC4 solar connectors
• AISI 4140 alloy steel construction, formed by dewaxing casting for accurate dimensions
• Compatible with CP-371, CP-336F, and 1PK-3003F crimp frames
• Sold as a single crimp head unit

Product Benefits

• Dewaxing casting manufacturing produces tight dimensional tolerances, ensuring each MC4 crimp meets the connector specification without over- or under-crimping
• AISI 4140 hardness sustains the die profile over many crimping cycles, preventing dimensional drift that would cause inconsistent contacts
• Compatibility with three widely used Proskit frames means the head integrates into an existing tool setup without adapters
• A dedicated MC4 head used with the correct frame eliminates the need for a separate MC4-specific crimping tool
