The McCoy Egress Series Heavy Duty Friction Stay is engineered to balance safety, operation, and longevity like no other. Made from austenitic SS304 stainless steel, these heavy-duty friction stays are perfect for side-hung vents in aluminum and uPVC windows. The McCoy Egress Series Friction Stay provides enhanced security, better weather resistance, and improved window functionality.
Biggest Advantage Of McCoy Egress Series Heavy Duty Friction Stay
Cleaning the outside glass surface of windows on higher floors is often challenging due to limited accessibility. The McCoy Egress Friction Stay is designed for corner opening with system integration, allowing easy cleaning of glass panels. Shifting the sash forward creates a gap that enables effortless cleaning of the outer glass surface. Additionally, the hinge remains in Egress mode after closing, ensuring safety and convenience during maintenance.
Features of McCoy Egress Series Heavy-Duty Friction Stay
Premium Material Construction (SS304 Stainless Steel)

The McCoy Egress Friction Stay is made using corrosion-resistant metals with superb mechanical properties, such as SS304 steel. It's austenitic stainless steel composition ensures that the hinges are suitable for residential and commercial properties, where exposure to severe environmental conditions is common.
With 17.5-20% chromium and 8-11% nickel in SS304 steel, great resistance to corrosion is guaranteed, which is highly sought after in coastal and industrial regions exposed to salt.
With a remarkable hardness of up to 360 BHN, ultimate tensile strength of up to 1180 MPa, and fatigue strength of 440 MPa, the McCoy Egress Friction Stay is regarded as one of the toughest hinges available.
Heavy Duty Load Capacity
Friction stays are offered in a variety of sizes to suit different sash weights: 12 inches (35 kg), 14 inches (38 kg), and 16 inches (40 kg). These sizes are designed to fit most window openings, whether in apartments or larger commercial buildings.
Egress Functionality for Safety
The importance of egress windows for safety during emergencies, such as fire breakouts, is well-recognized. The McCoy Egress Friction Stay has been designed to hold the window in the Egress position at 88°, escaping through the window easier. This functionality allows better ventilation as well as egress in case of emergencies, adding an extra layer of safety to any building.
The self-balancing functionality of the McCoy Egress Series makes it easy to use. An integrated friction adjustment screw allows the hinge to be set for different sash weights, reducing wear and tear over time. Additionally, the asymmetrical arrowhead end geometry and end cap design ensure tighter closure, which results in better resistance to wind pressure.
Weather Sealing
Excellent weather sealing has been specially designed into the McCoy Egress Friction Stay. Positive and negative wind loading in the closed position prevents drafts and the escape of conditioned air from the building. This is especially beneficial in regions that experience extreme weather, as the window will remain sealed and energy-efficient.
Resistance to Corrosion in Difficult Conditions
The McCoy Egress Series features SS304 stainless steel with Grade V corrosion resistance, which is exposed to a neutral salt spray for 500 hours without corrosion. This makes the steel perfect for use in coastal areas, industrial zones, or regions exposed to chemical and saltwater environments.
Benefits of the McCoy Egress Series Heavy-Duty Friction Stay
Longer Service Life: Due to the low wear characteristics of premium stainless steel, the friction stays require minimal maintenance and provide longer service lives.
Enhanced Safety: The self-balancing mechanism and Egress function ensure that windows remain safe and operational in emergencies.
Weather Resistant: Superior weather sealing combined with resistance to wind pressure ensures energy efficiency and comfort during various weather conditions.
Ease of Cleaning: Innovative design makes it easy to clean the outside glass surface, helping maintain the windows' appearance.
Corrosion Resistance: SS304 steel resists corrosion effectively, ensuring reliability in challenging environments, from coastal regions to industrial zones.
