The Decoranddecor 102mm Ball Bearing Door Hinge is designed for homeowners and contractors seeking a reliable, high-performance hardware solution for heavier internal and fire-rated doors. Its primary benefit is the precision ball bearing mechanism that ensures silent, fluid operation, though users should note that precise mortising is required for a flush installation on door frames.

These hinges are primarily engineered for internal and fire-rated doors.
Yes, they are tested to BS EN 1634 standards for 30/60 minute fire doors, provided they are installed according to fire safety guidelines.
Each hinge is rated to support doors up to 80kg.
The mechanism is designed for maintenance-free operation and generally does not require extra lubrication.
The hinge measures 102mm, which is equivalent to 4 inches.
The silver finish is designed for indoor use and coordinates with interior hardware.
Check if the mortise is deep enough for the hinge leaf to sit flush; re-chisel the rebate if necessary.
Verify the hinge is perfectly level; ensure no debris is trapped in the ball bearing housing.
Check for loose mounting screws and tighten them, or check if the door weight exceeds the 80kg limit.
For optimal performance, the hinges should be recessed into the door and frame using a router or sharp chisel to ensure they sit completely flush. When installing on fire doors, ensure the use of appropriate fire-rated intumescent pads between the hinge leaf and the door material, as required by fire safety regulations. For maintenance, the ball bearing mechanism is largely maintenance-free; however, keeping the area free of paint buildup during door decorating will preserve the longevity of the movement. Periodically check that all screws are tightened to maintain door alignment.
