Replacement belt for Marantec operators (for 8' operators)
The Marantec garage door opener belt may wear out over time and need replaced. The 8030279 Replacement Belt is the perfect replacement to get your Marantec belt opener back up and running again. To make sure you're ordering the correct belt measure the overall length of your existing belt. If your belts measures approximately 250" then you have a 8' opener and will use this belt. If your belt is shorter and measures 226-1/2" then use the 7' Belt (8020278) or the10' Belt (8030280) if it is longer and measures 297-1/2".
The belt has a Travel Limit Tab attached to it. The tab is what triggers the reference switch and tells the opener when to stop. Check the Belt Connector on your operator while you are replacing the belt. If it's worn or cracked it should also be replaced.
