PRODUCTS | Doric DN400 Twin Chainwinder

The Doric DN400 Twin Chainwinder continues to lead the way as the ultimate control system for large awning windows.

Providing a solution to the growing requirement of oversized awning openings in new developments, this groundbreaking product sets the benchmark for ease of operation.

Ultimately, the DN400 is changing the way in which awning windows are specified.

Following in the footsteps of the industry-leading Doric DS1 Chainwinder, the DN400 Twin Chainwinder allows for smooth, easy operation, control and installation, all in a secure, key lockable configuration.

In the case of form meeting function, the outstanding operation of the DN400 is complemented by a stylish and easy to use slim fold-down lever design, which stores neatly into the body of the chainwinder when not in use.

Adaptability is also core to the design’s success, with it being ideal for both residential and commercial settings.

Advantages of the system include a stainless steel chain, which can be removed from the sash plate to aid in installation and cleaning before clipping back into position.

The diecast Zinc body of the DN400 can be ordered in powder coated satin black, pearl white or silver, while custom colours are also available upon request.

Like all Doric products, the system has been thoroughly tested to ensure long-lasting quality operation. This development program has seen the DN400 surpass Neutral Salt Spray testing in accordance with AS 2331.3.1.

At the same time, it has also been tested and surpassed over 5,000 pascals of negative pressure, making it ideal for high rise applications or use in locations subject to high winds.

While the DN400 does not have a weight or load rating, when it is used in conjunction with the Doric Heavy Duty Stainless Steel stays or any continuous hinge framing system, it will efficiently operate within a sash up to and beyond 100 kg of load.

Notably, the DN400 Twin Chainwinder can be specified pre-restricted in accordance with the NCC, meeting the requirements of the ‘Kid’s Don’t Fly’ initiative. This means that the window opening can be no larger than 12.5 cm, or the size of a child’s head, and resistant to a force of 250 newtons, or approximately 25 kg, all while being robust and childproof. Restriction pins can be easily added via holes located underneath the assembly.

The DN400 can be specified keyed or non-keyed and features a push-button locking system.
