The Marantec 96834 Tab Replacement is a factory-specific belt-drive component used on select Marantec garage door opener rail systems. This small but critical tab secures the drive belt at the carriage/trolley connection point, helping maintain proper belt engagement and smooth, quiet door travel. It is intended as a direct replacement for a worn, damaged, or missing tab on Marantec belt-drive systems used in residential garage door applications. Because this is a model-specific garage door opener part, verify compatibility with your opener’s manual or parts diagram before ordering.
Installation typically involves disconnecting power to the opener, relieving belt tension, swapping the old tab for the new one at the trolley/rail assembly, and re-tensioning the belt per the manufacturer’s procedure. After replacement, you may need to check door balance and run a travel/force calibration or limits routine according to your Marantec opener instructions. No programming is required for the tab itself. For safety, work with the opener powered off, support the rail if needed, and follow all precautions outlined by Marantec. This OEM-style replacement is ideal for routine maintenance or repair when servicing a Marantec belt drive opener and is commonly searched as a Marantec 96834 belt drive tab, garage door opener replacement part, or trolley/carriage belt anchor for select Marantec units.
