ADDITIONAL BOTTOM PANEL SUPPORT TO PREVENT DOOR SAG
Double-end hinges provide additional support when your roll-up door is in the open position. When roll-up doors are open, there can be a tendency to sag — creating a risk of the door unrolling and striking staff and shipments, particularly with heavier door models.
Adding double-end hinges will add support to the bottom panel, reducing door sag and relieving strain on the rollers to prevent unwanted closure. Double-end hinges are used in conjunction with 5″ stem rollers (available in nylon or steel) to provide optimum support, increasing staff and cargo safety while allowing maximum clearance within the opening.
