Product Description

The CHAMBERLAIN k144c0056 is a chain idler pulley designed as a direct replacement component for Chamberlain garage door opener systems. The idler pulley guides and maintains proper tension on the drive chain, reducing slack and keeping the opener operating smoothly through its full range of travel.

It fits into the chain drive assembly and works in conjunction with the drive sprocket and trolley carriage. Typical installation occurs during routine drivetrain servicing or as part of a repair following chain derailment or excessive noise during door operation.
