Guardian Garage Door Opener Belt Assembly 8' Doors GUT-8B (11mm) Model 628
Guardian Garage Door Opener Belt Assembly 8' Doors 11mm Model 628 (and Others) I'm not exactly sure what operators these belts go to as there's not ANY info out there on them. What I have been able to figure out is that they for sure go to the model 628 (but I assume others as well). Also that this belt measures 11mm (roughly 7/16") across whereas the other Guardian belts that have a different end attachments and idler pulley are 9mm across (roughly 3/8"). I have those as well, search for GUT-7B in my store. Please know that IF you have the other belt and you're changing to this one you would have to change the idler pulley, so I recommend ONLY USE THIS BELT IF THE ATTACHMENT ENDS ON YOUR BELT LOOK THE SAME!!! - Belt Measures approx. 255”-257" end to end, including the permanent metal attachments. - Belt width is 11mm - Does not come with the attachment hardware, you need to transfer these pieces from your original assembly. FOR USE WITH 8 FOOT HIGH
