Product Description

McCoy Egress Series Heavy Duty (SS 304) Friction Stay (12 Inch)

Key Features:

• Heavy duty 4 bar friction hinges made from Austenitic SS 304 Steel suitable for Aluminium and PVC-U applications..
• With a Pitting Resistance Equivalent Number (PREN) of 20, and good resistance to Inter-Granular Corrosion, SS 304 is well serviceable in corrosive environments.
• In Normal position, opening for Egress is 88°.
• Sash can be shifted forward by unlocking the catch for easy clean option. The friction hinge re-sets to egress mode on closure.
• Specially designed for side hung vents for Aluminium as well as PVC-U Windows.
• Self Balancing with excellent weather sealing capabilities.
• Pressure adjustment screw for catering to different sash weights.
• Asymmetrical Arrow head End Point and End Cap ensure tighter closure and better resistance to Wind Pressure.
• Capable of withstanding positive as well as negative wind loads in closed condition.
• Easy to clean outside glass surface as the sash shifts sufficiently away from the jamb.
• Suitable options available for Side Hung Vent sizes upto 900 mm x 1500 mm. & Vent weights up to 50 kg.
• Grade V Corrosion Resistance - Tested for 500 Hours in Neutral Salt Spray solution for Corrosion resistance. (Certificate available on request)
• Successfully tested for 10,000 cycles of operation
• Asymmetrical arrow head end point and end cap
• Composite Stainless Steel and Plastic Slider
• Friction Adjustment
• Self Balancing capabilities
• Vent openable up to 88° in Egress position.
• Vent shifts ahead giving space for sticking out hand for Easy Cleaning of the outside Glass surface.

Technical Specification:

• Stack Height - 16.5 mm
• Base Channel Width - 22.5 mm
• Hardness of up to 360 BHN
• High Fatigue Strength of up to 440 MPa
• SS304 is composed of 17.5-20% Chromium, 8-11% Nickel, < 0.08% Carbon, 2% Manganese, 1% Silicon, 0.045% Phosphorous and 0.03% Sulphur.
• Young's Modulus of 200 GPa, Ultimate Tensile Strength up to 1180 MPa, Shear Strength up to 690 MPa.

Advantage:

• Asymmetrical End Point of the Sash mounting leaf enters the Asymmetrical End Cap on the Frame mounted leaf a little before hand, thereby ensuring perfect closure of the sash.
• Smoother and Stick - Slip free movement of Vent, low wear and tear and Self Cleaning of debris.
• Very good Mechanical Properties leading to ease of Load Carrying capacity.
• Low Wear and Tear due to low abrasion.
• Can withstand repeated loading and unloading cycles, so more Cycles of Operation can be achieved.
• Very Good resistance to Corrosion.
• Regulates the amount of Force required to open and close the window.
• Precludes the automatic closure of sash due to its own weight.
• Better ventilation and easy for person to jump outside in case of any Emergency, like out break of Fire.
• Easier to clean and maintain.

Benefits:

• The tight closure of sash entails better resistance to Wind Load.
• Longer Service Life and low maintenance.
• Longer Service Life
• Can be used in corrosive environment like proximity to Sea Shore or Chemical factories.
• Comfortable and easy to operate for the user.
• Safer as there is no chance of the sash closing down accidentally.
• Keeps room fresh and ventilated and also possibility of Emergency egress. Friction Hinge resets to Egress automatically, so safety is not compromised.
• Cleaning becomes easier, and also re-sets to Egress mode on closure, so safety is not compromised.
