The Genie 37557R.S Chain Bullet Assembly is a genuine OEM replacement connector for Genie chain-drive garage door openers. This assembly links the drive chain to the trolley/traveler on compatible Genie T-rail style systems, restoring proper movement of the door when the original connector is worn, damaged, or missing. It is commonly used during chain replacement, rail service, or drive system repairs to ensure smooth, reliable engagement between the chain and the opener’s carriage.
Designed specifically for Genie chain-drive applications, this replacement part helps maintain correct chain routing and tension for dependable residential garage door operation. Installation typically requires disconnecting power, releasing the door from the opener, relieving chain tension, and attaching the chain bullet to the trolley as outlined in your opener’s service manual, followed by re-tensioning and safety testing. Verify compatibility by matching part number 37557R.S in your opener’s parts diagram; this assembly is not intended for Genie screw-drive or belt-drive models.
