Designed and tested to support thrust loads or doors weighing up to 800 pounds. For those detention grade applications, they meet or exceed ASTM F1758 Grade 1 and are FBOP approved. They feature self-lubricating, maintenance free, radial and thrust bearings which have PV ratings as high as 28000 psi x fpm. A precision, ground stainless steel, maximum security hinge pin is welded in place.

N/A Series i-8500 hinges will function at the rated capacities providing the following specification is met:

1. The hinges are installed without inducing "hinge bind".

2. A minimum of 2 hinges (1 pair) are used per door.

3. Door weight or thrust load shall never exceed the thrust capacity of one hinge.

4. Compliance with bolting specification.

5. Minimum thread engagement into reinforcing member shall be equal to bolt diameter.

6. For weld on applications, the minimum fillet weld size shall be 1/4", and be full length on the top, bottom, and vertical edges of the mounting surface of each hinge leaf. There shall be no welding on the backside, adjacent to the hinge barrel. Assure the weld interpass temperature at the hinge barrel does not exceed 225 deg. F.

7. For certain high frequency applications, adequate load distribution between hinges maybe necessary to obtain the highest margin of safety with respect to load-life on bearings.
