The Sommer 10056 Carriage Pin 1 3/8" is an original OEM replacement pin designed for Sommer Direct Drive garage door opener systems. It secures the moving carriage (trolley) to the door arm linkage, creating a reliable pivot point so the opener can smoothly raise and lower the door. This part is commonly used when installing a new opener, replacing worn hardware, or restoring proper linkage after service.
Use by aligning the carriage and door arm holes, inserting the pin, and locking it in place with the appropriate retaining clip per the opener’s parts diagram. No electrical programming is required for this hardware swap, but always disconnect power to the operator and ensure the door is fully supported before working on the linkage. Intended for residential garage door applications on Sommer Direct Drive systems, the 10056 pin maintains factory-correct fit and function. Verify compatibility by checking your opener’s parts list or manual for part number 10056 to ensure an exact match.
