This is a genuine OEM sourced part which is specially designed for Chamberlain garage door openers. It is an identical replacement for a missing or a faulty chain idler pulley that was installed on a new unit. The purpose of this component is to apply tension on the chain that opens the door. Please make sure to refer to the appropriate diagrams of your model for the correct location and application of this part. This high-quality item is made of durable plastic and is sold individually. To perform this repair you will need a wrench set, a screwdriver, and pliers to take apart and reassemble the housing.
