The Genie 37561R.S Belt and Bullet Assembly (7') is a genuine OEM replacement for Genie belt-drive garage door openers configured for standard 7' doors. Designed to restore smooth, quiet operation, this assembly includes the drive belt with the factory “bullet” connector that interfaces with the opener’s trolley on Genie belt-rail systems. It is intended for residential belt-drive units that use Genie’s C-channel style belt rail; it will not work with screw-drive or chain-drive models.
Use this part when the original drive belt shows wear, fraying, or slippage, or when the bullet connector is damaged. Installation typically involves routing the belt around the opener’s drive sprocket and idler, engaging the bullet into the trolley, and setting belt tension per the opener’s manual, followed by rechecking and, if needed, recalibrating travel limits. Always disconnect power before servicing and verify compatibility by matching part number 37561R.S with the parts list for your specific Genie model and rail type. For doors taller than 7', select the corresponding Genie belt and bullet assembly specified by the opener manufacturer.
