With LiftMaster’s planned launch of their new UL 325 2018 compliant gate operators, they are announcing the discontinuation of part numbers associated with their old gate operators. Operator part numbers that had previously ended with “U” (i.e. CSW24U) will no longer be available come August 1, 2018. They will be replaced with a part number ending with “UL” (i.e. CSW24UL).
