U-type copper die set intended for use with a compatible compact crimper to produce cULus-classified crimps with manufacturer-specified connectors. Dies have laser-etched size markings and industry-standard color coding to identify die size. The crimping cycle imprints the wire size onto the connector to aid inspection. Connectors and crimper are sold separately; consult the crimper user manual for a compliant chart of dies and connectors.

Project Ideas

Business

Cut-to-Length Battery Cables Shop

Offer made-to-order 4 AWG cables with cULus-classified crimps using approved connectors. Customers pick color, length, lug hole size, and labeling; you deliver ready-to-install cables with heat-shrink and QC photos of the crimp imprint.


Mobile Marine/RV Crimping Service

Provide onsite cable fabrication and termination at marinas and RV parks. Diagnose high-resistance connections, replace lugs, and build new 4 AWG leads on the spot, documenting each crimp’s imprint for quality assurance.


Pre-Configured Kits (Solar/Winch/Audio)

Sell turnkey 4 AWG kits for popular inverters, winches, golf carts, and car-audio Big 3 upgrades. Include correctly sized lugs, fuses, boots, heat-shrink, and simple instructions—each kit assembled with compliant crimps for peace of mind.


Event Pop-Up Cable Bar

Set up at car shows, off-road meets, and hamfests to make custom-length 4 AWG cables while customers wait. Offer quick diagnostics, lug replacements, and printed QC cards featuring the crimp’s size imprint as proof of proper termination.


Crimping Masterclass + Content Funnel

Run workshops on selecting correct die/connector pairs, executing proper crimp cycles, and inspecting terminations. Monetize through ticket sales, tool/connector affiliate links, and selling your own pre-made cable kits.

Creative

Off-Grid Solar Battery Bank Cabling

Build custom-length 4 AWG battery interconnects and inverter leads for small/mid-size solar setups using approved copper lugs and a compatible compact crimper. The die’s imprint aids later inspection and labeling; finish with adhesive-lined heat shrink for corrosion protection.


Overland Van Dual-Battery Wiring Loom

Fabricate robust charge/ground leads, isolator connections, and quick disconnects (e.g., Anderson SB120 for 4 AWG) for a van/overland dual-battery system. Use the die’s cULus-classified crimps for vibration-resistant reliability and color-coded sleeves for clean routing.


Car Audio Big 3 Upgrade

Make 4 AWG alternator-to-battery, engine ground, and chassis ground cables for a clean, low-resistance path in car audio builds. The laser-etched die markings simplify matching dies to connectors, and the crimp imprint helps identify cable size during future upgrades.


Ham Shack DC Bus + Grounding

Build a fused 12–14V DC distribution bus fed by 4 AWG from a power supply or battery, plus equipment bonding to a ground bar/rod with tinned lugs. Use the die to produce inspection-friendly crimps and organize with labeled heat-shrink for tidy station wiring.


Marine Trolling Motor/Winch Rewire

Replace corroded leads with marine-grade tinned 4 AWG cable and lugs for trolling motors or anchor winches. The die’s imprint supports ABYC-style inspections, while adhesive-lined heat-shrink and boots keep saltwater at bay.
