In February of 2009, Helton/FlexiForce introduced 5/16” back hang slots for Residential Horizontal Door Track. This product enhancement was very well received, so we would like to take this opportunity to remind everyone of the importance of utilizing this feature. These slots enhance the ability to attach the back hang approximately 18”-24” from the free end of the door track. Reducing the unsupported span improves the overall stiffness of the installed track system. Back Hang Slots continue to be effective for all Dura-Hem Horizontal Door Track up to 0.051” material thickness, and for doors up to 10’ high. Track for doors greater than 10’ high are typically equipped with full length horizontal angles, making additional back hang slots unusable on taller track sets. Please contact your Sales Representative if you have any questions regarding the use of this feature.
