OVERVIEW

Bifold door hinges connect the door to the building (at the top of the door) and join the top and bottom halves of the door together (at the center of the door). Durable hinges are essential to the safety and security of the bifold door.

At Diamond Doors, we manufacture our hinges using a cold roll forming technique that provides about 20% more strength to the hinge. Our hinges also use a one piece design with multiple hinge knuckles. Added knuckles help distribute the loads of the door more evenly across the hinges and door header. Together, these unique features increase the strength and longevity of the hinges, adding safety and durability to your door.

We also use an exclusive hinge bushing design to create a hinge that functions smoothly and quietly without regular greasing. This makes our door hinges a truly low maintenance option for your bifold door.

OVERVIEW

The Genesys electrical box controls the operation of the bifold door, connecting the up/down/stop controller to the bifold door motor. It includes open-close limit switches, thermal overloads, fuses, and our innovative circuit board.

The circuit board is the center of it all. It offers on-board diagnostics, plug-n-play installation on future door upgrades, built in emergency overrides, and other features that make the Diamond door a convenient door option.

The open-close limit switches determine how far the door opens and closes. We pre-set the closed limit switch in-factory, while the open limit switch requires its final adjustments once the door is installed. These instructions can be found in the electrical manual.

Thermal overloads provide protection for the door’s electrical components. If the overloads detect a large amperage draw, they cut off the power to the door to avoid damage. These overloads automatically reset within 30 seconds if an overload occurs.

We install the wiring and electrical components for your door in-factory, including a junction box at the top of the door. This makes connecting to your building’s electrical system hassle-free. Diamond doors require no onsite electrical connections on the door frame and you can get your door up and running quickly and efficiently.

The Genesys electrical box can be connected to single phase 230V, three phase 208V, and three phase 460V, depending on the electrical power available on your building site.

Rating and Certifications

The Genesys electrical box is UL325 certified, meaning that is certified for use in commercial applications. Our electrical box itself meets NEMA 4/4X/12 and IP64 specifications, protecting the electrical components inside from dust and water damage.

OVERVIEW

Our industrial grade gearbox is an integral part of the Diamond Doors lift system, connecting the electric lift motor to the driveline. The gearbox is mounted at the center of the door, connecting two drivelines that operate simultaneously as the door opens and closes. The center mount design allows for greater flexibility in opening speed and lifting capacity.

With a gearbox ratio that ranges from 32:1 up to 90:1, our gearbox and lift system provide a standard opening rate of 18 feet per minute. This is the fastest standard opening rate in the bifold door industry, giving you quicker access to your hangar or equipment. (We also offer a speed increase kit which increases the opening rate by 20-25%. Please talk to our sales team for more information.)

Our gearboxes are rated for continuous use, which is far above what is necessary for even the most frequently used doors. This ensures a long-lasting lift system and reliable door operation.

OVERVIEW

All Diamond doors come standard with our two-part polyurethane paint to protect your door frame against everyday wear and tear, rust, and scratches. This long-lasting paint reduces flaking and fading and provides an attractive finish that is easy to maintain.

Our standard colour is the Diamond Doors charcoal gray (QC 58053). However, a wide variety of custom colours are available on request. To specify a custom colour, we will need an RAL or QC number.

We also offer a powder coat finish, which is available in varying textures and colours. Powder coating is an extremely durable finishing option and is well-suited to harsh environments.

OVERVIEW

The Diamond Doors lift motor, part of the lift system, provides convenient door operation with the push of a button.

All Diamond doors are designed with an AC induction electric brake motor, coupled to the gearbox to create a reliable lift system. The integrated brake system ensures safety when power is cut to the door by holding it in the open position in case of a power outage.

The size of the motor is determined by door weight, door size, and opening speed that is required. Most motors range in size, including ¾ HP, 1 HP, 1.5 HP, 2 HP, 3 HP, 5 HP, and 7.5 HP. We align the motor size and power with the appropriate gearbox specifications to create a long-lasting lift system by ensuring that the gearbox is not under strain.

Our electric motors are available in single phase 230V, three phase 208V, and three phase 460V, depending on the electrical power available on your building site.

OVERVIEW

The driveline is an important part of the lift system. As the lift motor operates, it turns the driveline, wrapping the lift cables and opening (or closing) the door. Our driveline offers low maintenance reliability, with fewer moving parts and a simplified design. Its unique design also prevents our lift cables from overlapping, which is the primary cause of shortened cable life.

The size of the driveline is determined by the size of your door, gear ratio, and the required opening speed. A series of industrial grade pillow block bearings join the driveline to the lower internal truss.

OVERVIEW

Column support angles are designed for straight wall wood buildings as additional structural support while your bifold door is open.

When a bifold door is open, the door rollers push on the door post. Over time, this can cause the wood to bow and warp. The column support angles brace the top of the post where the roller loads are the greatest to prevent damage to the door post.

Column support angles are made from 10 foot long, 5 x 3 angle, finished in a high quality polyurethane white paint. They are fastened at the top of the door post by the outer hinge mounting bolts and additional provided structural screws.

OVERVIEW

Column followers are a wind protection option used on steel buildings and the self-supporting header system. They prevent the bottom section of the door from pushing outward when wind or positive air pressure is present inside the building.

Column followers are located at the bottom of the door, toward the interior of the door frame. They slide along the inside flange of the building column or self-supporting header frame as the door operates, holding the door against the building.

The solid steel column follower pin is sleeved in a nylon bushing to reduce noise and provide smooth, quiet operation. They are easily adjustable to accommodate different flange depths.

OVERVIEW

The cable anchor kit is included in wood building and quonset door packages to provide structural support while your bifold door is open. The kit reduces the outward pull of the door on the door header by transferring the load further back into the building.

The kit includes ¼” 9-17 wire rope cables, cable anchor brackets, and mounting hardware. The number of cables required is dependent on door size and load.

For wood buildings, the cable anchor kit attaches to the backside of the door header and to the top plate or post on your building’s side wall. Door installers can anchor the cables into the side wall at a 45 degree to 90 degree angle from the end wall, as illustrated in the photo gallery.

OVERVIEW

The emergency manual opener is designed as a back-up to open and close the door in case of a power outage. Each custom designed electric motor is equipped with a hex shaft located on the top side of the motor. With the appropriate socket, you can conveniently spin the motor shaft to open or close the bi-fold door manually. Refer to your owner’s manual for proper procedure.
