For larger trailer projects or workshop stock, this 500-foot roll of East Penn 4-conductor trailer wire provides ample length for extensive wiring runs. Colour-coded conductors (yellow, white, green, brown) stay bonded together through installation, then separate cleanly for final termination.

The 16-gauge stranded copper core balances conductivity with ease of routing through tight spaces. Manufactured to SAE J1128 and SAE J378 standards with PVC insulation, it’s ideal for RVs, marine vessels, and utility trailer applications.

• 4-wire parallel bonded with colour coding
