Eai - 3" Internal Door Hinges & Screws G7 Fd30 - 76X50X2mm Square - Black - Pack 3 Pairs

This pack contains 3 pairs of Eai 3" Internal Door Hinges.

No, these hinges are designed and intended for internal doors only. They are not built to withstand outdoor elements.

For most standard internal doors, one pair (two hinges) is typically sufficient. For heavier wood or glazed doors, 1.5 pairs (three hinges) are recommended.

Yes, screws are included with the hinges. However, for very heavy doors or if installing into softer wood, consider using higher-quality, longer screws for a more secure fit.

The dimensions are 76mm x 50mm with a 2mm thickness, and they have a square profile.

Clean with a soft, dry cloth. Use a damp cloth for marks and dry immediately. Avoid abrasive cleaners.

Ball bearing hinges have ball bearings within the knuckles that reduce friction, leading to smoother, quieter operation and increased durability compared to standard plain bearing hinges.

Apply a small amount of light machine oil or graphite lubricant to the hinge pin and ball bearings. Ensure no obstructions are present.

Verify that 1.5 pairs of hinges were used for heavier doors. Check if screws are fully tightened. Ensure the door and frame are not warped.

Ensure the mortise cutouts in the door and frame are the correct size and depth for the hinges. Consider pre-drilling pilot holes for the screws.

Minor scratches may be touched up with black paint suitable for metal. Avoid harsh cleaning chemicals that could further damage the finish.
