Restricted friction hinges offer a convenient and cost-effective way to upgrade existing windows, enhancing security, functionality, and aesthetics. By following these steps, you can seamlessly integrate these hinges into your windows with minimal friction.

Tools and Materials:

Restricted friction hinges

Drill and bits


Measuring tape


Safety glasses

Step-by-Step Instructions:

a. Remove Existing Hinges:

Wear safety glasses.

Determine the type of existing hinges and appropriate replacement screws for the new restricted friction hinges.

Remove the screws holding the existing hinges in place.

Carefully lift off the old hinges from the window frame and sash.

b. Position New Hinges:

Place the new restricted friction hinges on the window frame and sash according to the manufacturer’s instructions.

Use a level to ensure they are aligned correctly.

Mark the screw holes using a pencil or other sharp object.

c. Drill Pilot Holes:

Wear safety glasses.

Using a drill with an appropriate-sized bit, drill pilot holes at the marked screw locations.

The pilot holes should be slightly smaller in diameter than the screws.

d. Install Hinges:

Drive the screws through the pilot holes and into the window frame and sash.

Use a screwdriver to tighten the screws securely, but avoid overtightening.

Repeat for all the new restricted friction hinges.

e. Adjust Hinge Tension:

Locate the adjustment screw on the hinge.

Use a small hex key or screwdriver to adjust the tension as per the manufacturer’s recommendations.

Test the window for smooth operation and optimal friction resistance.

f. Secure Cover Caps:

If the restricted friction hinges come with cover caps, snap them into place over the screws to conceal them and enhance aesthetics.

g. Final Inspection:

Open and close the window multiple times to ensure it operates effortlessly.

Check if the screws are properly tightened and the hinges are firmly secured.

Make any necessary minor adjustments to optimize the performance and appearance of the upgraded windows.

Additional Tips:

Consider the weight of the window when selecting the appropriate hinge size and quantity.

Use stainless steel or zinc-plated screws for durability and corrosion resistance.

If the screws are too long, they can penetrate through the window frame, weakening its structural integrity.

If you encounter any difficulties during the installation process, consult with a professional handyman or window repair specialist for assistance.
