The Genie 37561T.S Belt and Bullet Assembly 10' is a genuine OEM replacement belt for Genie belt-drive garage door openers that use a 10-foot belt rail system. Designed to restore smooth, quiet operation, this assembly includes the pre-attached “bullet” connector that links the belt to the opener’s trolley for reliable travel. It is intended for use on systems configured for 10-foot door height rails and is not interchangeable with chain-drive or screw-drive models.
For compatibility, match the part number on your opener’s rail or in the owner’s manual; this 37561T.S belt fits Genie belt-drive units that specifically call for the 10-foot belt and bullet assembly. Installation typically involves unplugging power, placing the door in manual release, routing the belt around the idler pulley and motor sprocket, connecting the bullet to the trolley, and setting belt tension per Genie’s instructions, followed by rechecking travel limits and force settings. Always verify the door is properly balanced and avoid overtensioning. This OEM replacement is ideal for residential garage door opener repair where a 10-foot Genie belt rail is used, providing a dependable fix for worn, frayed, or broken belts while maintaining manufacturer-specified performance.
