A Diamond door is a great choice for your building.
Here’s a few reasons why.
Get a Larger Door Opening.
Bifold doors provide a clear opening that is wider and taller than what is possible with an overhead door. In addition, because they are mounted to the exterior of the building, the self-supporting header allows you to install the door above your building’s roofline.
Make Your Door Easier to Use.
A Diamond door makes it easier to access your building. Compared to sliding doors that are frequently difficult to move, bifold doors open at the push of a button. Add the remote opener and autolock package to make it even simpler.
Spend Less Time on Door Maintenance.
Designed with fewer moving parts and built from quality materials, you can expect to spend less time on maintenance with a Diamond bifold door. Instead, you can spend more time on what matters to you. Diamond doors are low maintenance and reliable.
Designed for Easy Installation.
We deliver your door directly to your building site – pre-assembled and ready for installation. And if you need someone to handle the install for you, we have a wide network of great door installers across North America.

We absolutely looove it. We also did the optional autolock system that allows the door to open and close with the push of a button. It’s amazing… I can fly over, hit the button, and the door is open ready for me to taxi right in.

We’ve had our door installed for a few months now and it has worked flawlessly. It opens fast, quietly and smooth. Best hangar door out there for the money!

My favourite feature would be the autolocking system. It’s very nice to know that the door, when it’s closed, is pulled tight and seals properly.

Why choose an Autolock?
We build our doors on simplicity and convenience – and our locking systems are no different. Many other bifold door manufacturers use systems operated by cables, straps, or springs. We’ve gotten rid of these complicated moving parts and created a low maintenance and reliable locking system. Here are two great ways the autolock adds even more convenience to your door.
Save Valuable Time– if you frequently use your bifold door, you’ll quickly find out that taking time to manually lock and unlock your door is a hassle. And while this may not be an issue if you only use your door once or twice a week, it’s another story if you’re using your door every day – or even multiple times a day. With the autolock package, it’s an easy way to save time and give you more time where you need it.
Stay Warm and Dry – when you add the remote opener to your autolock package, the weather won’t be a problem, as you can operate your door from wherever you’re sitting. You’ll stay comfortable, no matter the weather.
Down to the Basics

The Lock Rods
Our rotating lock rods press the locking fingers into place, securing the door against the building frame. We adjust these in-factory, which means you won’t have to adjust them when your door arrives.

The Locking Fingers
Attached to the ends of the lock rods, the locking fingers press tightly against the locking catches. The mechanics work very similarly to a vise grip design, creating a tremendous amount of leverage. This creates a strong seal between the door and the building.

The Locking Catches
The locking catches are fastened directly to the building, creating the connection from the door locking fingers to the building. These catches are adjustable, allowing the door to seal perfectly to your building.
