ILSALNS-4-14 ILSCO- #4 Aluminum Compression Lug

The ILSCO ALNS-4-14 is rated for aluminum conductors (#4 AWG). While the tin-plated barrel helps reduce galvanic corrosion, this lug is listed specifically for aluminum. If you need a dual-rated (AL/CU) lug for copper conductors, we carry alternative ILSCO and other brand options — contact us and we'll find the right fit.

ILSCO Surecrimp lugs are designed for use with ILSCO's proprietary Surecrimp dies and compatible compression tools. The correct die index for a #4 AWG aluminum lug will be specified in ILSCO's tooling chart (available on their cut sheet at the link above). Using the correct die ensures a gas-tight, code-compliant crimp — contact us if you need help sourcing compatible tooling.

Yes — the ILSCO ALNS-4-14 carries both UL and CSA listings, making it fully acceptable for use in Canadian installations under the Canadian Electrical Code (CEC). The CSA listing ensures the lug meets Canadian standards for aluminum compression terminations in panelboards, switchgear, and service equipment.
