Why Diamond Doors
Quality custom bifold doors engineered for convenience, innovation, and longevity.
-
Autolock system
Our locking system is engineered specifically for bifold doors, not adapted from a generic design. It locks and unlocks automatically, so the door opens and closes with the push of a button and stays secure when closed.
-
Aircraft grade lift cables
We lift with aircraft grade steel cables rated at a 10X safety factor. Unlike straps, steel cable won’t stretch, fray, or break down in sun and cold, so the door stays balanced and lifts evenly for years.
-
Low maintenance
Greaseless, maintenance-free hinges and fewer moving parts mean no regular servicing, so your door is a tool that makes life easier, not another piece of equipment to look after.
-
Maximum headroom
Our self-supporting header lets the door install past the roofline, giving you the most overhead room possible. It also suits retrofits on existing buildings, including quonsets and mitered corners.
