Functional, high-quality bifold door hardware designed for smooth operation, security and clean modern styling.

Strong and robust, it is capable of pulling in heavy panels without the need for additional D-handles. They drive shoot bolt locking and have a key locking facility as standard.
Our Pendulum handles are smooth, sleek handles, available on both intermediate styles and traffic doors. They are strong and robust making them capable of pulling in heavy panels without the need for additional D-handles. They drive shoot bolt locking and have key locking facility as standard.
D-handles are an optional handle used in conjunction with the intermediate handles. They are ergonomically designed, easy to use and fitted only to the inside of the doors.
Integrated into the hinge, they provide a solid hand-hold for pulling and sliding the doors open and closed.
Four-wheel bogie assemblies travel on twin stainless steel tracks to deliver smooth, graceful operation.
The bogie wheel assemblies support the full weight of the doors and include a dedicated guide running inside the outerframe for added stability and increased security.
On suitable traffic-door configurations, high-strength buffer magnets may be fitted to hold the traffic door against the adjacent panel in an open position.
They also act as a buffer, helping prevent traffic door handles from knocking against adjacent panels.
A traffic door allows quick and easy access from both inside and outside without needing to slide and fold back the main bifold panels.
If your chosen style does not allow for a traffic door, there will be no outside access and at least two panels must be folded to open the doors.
Bi-folding doors slide in pairs, so an uneven number of panels folding in one direction creates an odd panel that can operate independently. This panel is known as a traffic door.
Durafold 1000 bifold doors have been designed with security in mind, combining robust hardware, secure glazing and dependable locking points for confidence every day.
When anyone has new windows or doors installed in their home, security is always at the forefront of their mind. That is why all of our doors have been designed and manufactured with security in mind, giving excellent security without compromise.
From high security multipoint locking and superior cylinders through to internally glazed units and anti-jemmy bogie guides, every detail has been developed to help keep the system safe, secure and dependable.
Traffic doors are fitted with high security multipoint locking as standard. The lever-lever operated mechanism provides six locking points, including deep throw hook locks, a latch, dead bolt and adjustable roller cams to pull the door in tight for added security and weather performance.
The cylinder used on these doors is designed to deliver greater protection than a standard euro cylinder, with resistance to picking, bumping and drilling, plus a sacrificial break slot to improve security in the event of attack.
Even though intermediate handles are generally positioned internally, they still include key locking as standard for extra peace of mind. They can also be keyed alike so one key can operate all intermediate handles on the bifold.
Heavy duty shoot bolts secure the top and bottom of each intermediate panel. Operated by a pendulum handle, they are designed for a tight fit, smooth engagement and strong compression, helping create a solid barrier against forced entry.
The bogie wheel assemblies run with a dedicated guide inside the outerframe channel at the top and bottom of the doors. This adds strength, stability and anti-jemmy protection, helping prevent the panels from being forced off track.
Toughened safety glass is supplied as standard, with sealed units internally glazed using a high security bead. Because the units are installed from the inside, they can only be removed internally. Laminated security glass is also available as an upgrade.
