The Marantec 196669 Bumper Kit is a genuine OEM replacement part designed for select Marantec garage door opener rail assemblies. Positioned at the ends of the belt-drive rail, these bumpers act as cushioned stops for the trolley, helping to absorb end-of-travel impact, reduce noise, and protect the trolley and rail from unnecessary wear. It is commonly used in residential applications on Marantec systems where a rail-mounted bumper is required to ensure smooth, quiet operation and consistent door travel.
As a direct replacement part, the 196669 Bumper Kit installs on the rail ends in place of worn or missing bumpers. After installation, verify and, if needed, re-adjust opener travel limits and test the safety reversal system per the opener’s manual. For compatibility, match the part number to your opener’s parts diagram or consult Marantec documentation for your specific rail and Synergy-series opener. Always disconnect power before service, ensure the door is balanced, and perform a full operational test after the repair.
