Product Line Transition
We are transitioning this product line from Selterm to NSPA BCLP-series tinned copper lugs. During this transition, you may receive a mix of brands in your order.
Rest assured, you will receive a certified tinned copper lug matching the selected wire size and lug configuration. Manufacturer markings, finish, pad dimensions, and other minor physical details may vary slightly.
Installer Tips
Confirm the fit before crimping: cable construction can vary between manufacturers, and some nominal AWG cables may run slightly larger or smaller. Compare the stripped conductor with the lug barrel before completing the crimp.
These lugs are intended for stranded copper conductors. For best results, use a properly sized hex, dieless, or manufacturer-approved crimping tool suitable for the lug and conductor.
After crimping, inspect the connection for complete conductor insertion and a firm mechanical bond. Finish the connection with adhesive-lined heat shrink to provide added strain relief and environmental protection.

Great product, great service. Had to buy a new crimper. Batteries so far are fantastic.
Crimp Lugs are excellent quality. Thanks for crimping them onto the cable I ordered.
