HEX Aluminium Mechanical Connectors – Single & Double Barrel, One-Hole Mount, #6 AWG to 1000 kcmil

HEX aluminium mechanical connectors are set-screw lugs with a one-hole mounting palm: the conductor is clamped by a screw, so no crimping is needed. Single-barrel (HLA) connectors take one conductor, from #6 AWG to 1000 kcmil; double-barrel (HL2A) connectors take two, from 1/0 AWG to 1000 kcmil. They are aluminium, electro-tinned, and other types — two-hole palms, three-hole palms, multiple screws — can be made to order. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).
