Heavy Duty Fire Rated Concealed Leaf Aluminum Full Mortise Continuous Geared Door Hinge

• Door Reinforcement not required
• Includes Dril-Kwik screws and sex bolts
• Fire rating up to 3 hr. metal and 90 min. wood composite
• Prevents fingers from being pinched - enhanced safety
• Distributes door weight along the entire length of the frame to prevent sagging

The Continuous Geared Hinges are designed to last the life of a building. The unique design reduces the high amount of stress normally associated at the top of the door and frame on butt hinge applications. This keeps the door in constant alignment and eliminates the chance of door sag, making it ideal for high-use environments.

Note: All standard length hinges are supplied slightly shorter than nominal door height to avoid threshold or flooring clearance problems.
