BrochureProduct Data SheetArch SpecsShop DrawingsWarranty
Designed for door openings up to 25 feet wide, the springless and direct-drive HD-DD 2555 offers the benefits of our heavy-duty, HD Series rubber door design and fits into locations with as little as 20 inches of headroom.
With the elimination of counterbalance springs, direct-drive models are reliable for environments that require high-speed operation on high-cycle door openings, because springs are normally the main wear item on a door. Our patented aluminum bottom bar makes it possible to reset the door quickly following a vehicle impact, which keeps traffic flowing and eliminates downtime in busy operations.
