U‑type copper crimping dies intended for use with a compatible compact crimper and matching connectors. The dies produce cULus classified crimps on copper connectors across sizes from #8 through 600 MCM. Each die is laser‑etched with its size and uses industry‑standard color coding to identify sizes. After a completed crimp cycle, the connector receives an imprinted wire size for inspection. Connectors and crimper are sold separately; the kit includes a carrying case.
Project Ideas
Business
Mobile Heavy‑Gauge Crimping Service
Offer on‑site termination for electricians, solar installers, marine/RV techs, and facilities. Bring a compact crimper and this die set to produce cULus‑classified crimps up to 600 MCM. Provide photo documentation, the die‑imprinted gauge on each connector, and a quick QA sheet for inspectors. Price by termination and travel zone.
Custom Cable Assembly Shop
Sell made‑to‑order copper cable assemblies: inverter/battery leads, marine jumpers, EVSE feeders, generator whips, and car audio kits. Let customers choose gauge (#8–600 MCM), lug type, stud size, and length. Include adhesive heat‑shrink, serial labels, and a test/inspection report that references the die size and a pull‑test value.
Commissioning & QA Remediation
Partner with contractors to inspect, re‑terminate, and document heavy lugs before AHJ inspections. Use the die set to re‑crimp questionable terminations and leave connectors with imprinted wire size for easy verification. Deliver a punch‑list and close‑out package to help projects pass the first time.
Tool Rental + Concierge Kit
Rent a compatible compact crimper with this 15‑piece die set, plus an assortment of copper lugs, heat‑shrink, and a sizing chart. Offer optional on‑site setup or virtual guidance. Charge a refundable deposit, a day rate, and per‑connector fees for consumables.
Trade School & Contractor Training
Run hands‑on workshops teaching die selection, proper crimp technique, strain relief, and documentation. Use the die set’s color coding and imprint feature to standardize student outcomes. Provide certificates, and sell starter kits (dies, lugs, heat‑shrink) as an upsell.
Creative
Off‑Grid Battery Bank & Inverter Build
Design and assemble a compact battery bank with a DC distribution panel for a shed or van. Use the die set to make cULus‑classified crimps on 1/0–4/0 and up to 400–600 MCM lugs for main battery and inverter cables. The laser‑etched sizes and imprinted wire gauge on each completed crimp make it easy to document and verify connections. Add adhesive heat‑shrink and labels for a clean, pro look.
Industrial Copper Cable Sculpture Lamp
Create an industrial art lamp or sculpture using thick, de‑energized copper cable and crimped lugs as design elements. Form sweeping cable curves, crimp decorative terminations with different die sizes for texture, and mount to a metal or hardwood base. Use low‑voltage LED lighting with a separate power pack for safety, letting the crisp crimp imprints and color‑coded accents become part of the aesthetic.
Custom Welding Lead Kit
Build a set of quick‑change welding leads for a mobile cart. Crimp heavy‑duty lugs on #2 to 1/0 cable for stingers, grounds, and extensions, using the die imprints for easy size verification. Add protective boots and color‑coded heat‑shrink that matches the die colors so leads can be identified at a glance.
Show‑Car Audio Power Upgrade
Fabricate a high‑current DC harness for amps and the ‘Big Three’ upgrade. Crimp 1/0–2/0 copper lugs for battery, chassis ground, and alternator runs. Use the die’s cULus‑compliant crimps and imprinted size marks to please judges and inspectors, and finish with braided loom and labeled heat‑shrink for a polished trunk bay.
Crimp Quality Demo Board
Build an educational board that contrasts correct vs. incorrect terminations across sizes #8 to 600 MCM. Include cross‑sections, pull‑test notes, and the die‑imprinted wire size on each sample for teaching apprentices or clients what a code‑compliant crimp looks like.
