Richards Aluminum Compression Lugs: AL, SAL, AL-N, ALCD, TAL, APT and AL-4N

July 15, 2021

Richards aluminum lugs are made of high-conductivity aluminum, tin plated, and accept both aluminum and copper conductors. They are filled with an oxide-inhibiting compound and marked with conductor size and die information. For untinned versions, add “-NT” to the part number (SAL3-NT, AL3-2N-NT). Tables below follow the Richards connector catalog. Dimensions are in inches. For other sizes, contact Powertech Associates.
