Installation Instructions
Proper installation is crucial for the optimal performance and longevity of your hinges. If you are unsure about any step, it is recommended to consult a professional.
Tools Required:
- Pencil
- Measuring Tape
- Chisel
- Hammer
- Drill with appropriate drill bits
- Screwdriver (manual or power)
- Safety Glasses
Installation Steps:
- Prepare Door and Frame: Ensure that the door and door frame are properly prepared with mortises (recesses) that match the dimensions of the hinge leaves (3.5" x 3.5" with 5/8" radius corners). The depth of the mortise should allow the hinge leaf to sit flush with the surface.
- Mark Screw Holes: Place one hinge leaf into the prepared mortise on the door edge. Use a pencil to mark the locations for the screw holes. Repeat this for all hinges on the door.
- Drill Pilot Holes: Using an appropriate drill bit (slightly smaller than the screw diameter), drill pilot holes at the marked locations. This prevents wood splitting.
- Attach Hinges to Door: Secure the hinge leaves to the door using the provided screws. Ensure the hinges are flush and firmly attached.
- Position Door: Carefully position the door within the door frame, aligning the hinges on the door with the mortises on the frame. Use shims if necessary to maintain proper spacing.
- Mark Frame Screw Holes: Once aligned, mark the screw holes on the door frame through the hinge leaves.
- Drill Pilot Holes (Frame): Drill pilot holes into the door frame at the marked locations.
- Attach Hinges to Frame: Secure the hinges to the door frame using the remaining screws.
- Test Operation: Open and close the door several times to check for smooth operation and proper alignment. Adjust screws if necessary to achieve optimal performance.
Important: Always use appropriate safety gear, such as safety glasses, during installation.
Functionality
The Emtek 91033 plain bearing hinge is designed for smooth and consistent door movement. Once properly installed, the hinge allows the door to pivot freely between its open and closed positions. No specific operational steps are required beyond normal door usage.
- Smooth Movement: The plain bearing design ensures a consistent pivot action.
- Durability: Constructed from stainless steel for long-lasting performance.
Maintenance
Regular maintenance can extend the life and ensure the smooth operation of your Emtek hinges.
- Cleaning: Clean the hinges periodically with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish.
- Lubrication: For optimal performance, apply a small amount of silicone-based lubricant to the hinge pin and knuckles annually, or if squeaking occurs. Wipe off any excess lubricant.
- Tightening Screws: Periodically check all mounting screws for tightness. Loose screws can lead to door sagging or improper operation. Tighten gently to avoid stripping the screw heads or wood.
- Inspection: Inspect hinges for any signs of wear, damage, or corrosion. Replace hinges if significant damage is observed.
