3L320 Replacement Belt for LiftMaster SW420GL
The drive belt is an important component within the LiftMaster SW420GL mechanical drive system, transferring rotational power between the applicable motor, pulleys and other drive components during gate operation.
Over time, V-belts can experience stretching, cracking, glazing, fraying or general deterioration. The LiftMaster K16-3L320 provides the applicable 3L320 replacement belt when servicing compatible SW420GL operators.
