As a totally bespoke window, the OW-80 can be made to fit almost any size and configuration. Here are some of the more popular configurations available with OW-80, which includes top hung, right hung, left hung, French windows and fixed frames:

Additionally, the hinges found on OW-80 are made of corrosion-resistant stainless steel and have been cycled tested to 50,000 cycles. Hinge guards feature patented anti-slip and lock technology as standard along the hinged side of the window. All window hardware is covered in our 20 year guarantee, giving you complete peace of mind that you, your family and your belongings will be safe and secure.
