  • I need a replacement belt for our Genie model GPS1200IC, can you tell me which belt to order. Thanks, KC

    Unfortunately there are no belts for the Genie model GPS1200IC, we would recommend replacing the complete unit.  Sorry for the inconvenience.

  • What is the total length of the 7' door belt and the 8'door belt in standard measurement ie 18'

    The 7 foot door belt 39354R.S is 217 inches long for the belt only and 224 inches long including the belt and bolts. 
    The 8 foot door belt 39354S.S is 240 inches long for the belt only and 247 inches long including the belt and bolts.

    Both of these measurements do not include the turnbuckle.

  • Is there are replacement part for the belt clip and link so i can shorten then belt?

    This belt clip is not available separately and we do not recommend attempting to shorten this style of belt rail.

  • Will this work with 7055 D ??

    No, it will not. The SilentMax 1000 model garage door opener would use the 37561R.S belt.

  • Instructions says "This repair will require removal of the unit from it’s mounting hardware" Is there reason for that? It was really easy to route replacement belt through idler pulley and around around sprocket and then connect (tight) using turnbuckle. Without taking unit of the mount. have i done it wrong?

    If you got the belt replaced, you did not do it incorrectly. The recommendation is because some people may not be able to work on the ladder above their heads and find it easier to take it down to replace it.
