Lunar Series Die Set for Open-Barrel Contacts, AWG 20-10 – Pro’sKit 300-039

Eclipse Tools 300-039 — Lunar Series Die Set for Open-Barrel Contacts

The Eclipse Tools 300-039 is a Lunar Series interchangeable die set engineered specifically for open-barrel contacts. Its three-nest profile is sized for AWG 20-18, 16-14, and 12-10 to deliver reliable, repeatable crimps on uninsulated terminals. Optimized for D-sub, Molex, and AMP-style pins, this die helps installers and assemblers achieve consistent conductor and insulation crimps that hold up under pull and vibration. The die-only format drops into Eclipse Lunar and CrimPro crimp frames to expand capability or replace worn tooling. Using the correct open-barrel die minimizes rework, improves quality control, and keeps production lines and field teams moving. It is a practical addition for harness assembly, panel wiring, and electronics service. Keep one staged for common wire sizes to reduce changeover time between jobs. Supported locally from our Mesa, Arizona counter for customers in Phoenix, Mesa, Chandler, Tempe, Gilbert, Scottsdale, and Glendale, with fast nationwide shipping.

Each cavity is profiled to properly fold and capture the open-barrel wings around the conductor and insulation, helping maintain geometry and contact integrity. Whether you are outfitting an OEM build, standardizing an MRO toolkit, or supporting low-voltage field installations, this die set provides consistent results across teams and projects.
