10RH35 3-1/2 x 3-1/2-Inch Residential Hinge, 5/8-Inch Radius

Usually Ships: 1-3 Days

The Cal-Royal 10RH35 is a residential-weight, full-mortise plain-bearing hinge measuring 3-1/2 inches high x 3-1/2 inches wide when open, with 5/8-inch-radius corners. The five-knuckle design supports a compatible swinging door while the recessed leaves sit in matching preparations in the door and frame.

Practical Uses

• Interior residential doors: Consider for compatible low-frequency openings after checking the door weight, dimensions, and required hinge arrangement.
• Matching existing rounded mortises: The 5/8-inch corner radius helps identify the correct preparation, rather than selecting by overall size alone.
• Replacement and renovation: Coordinate the selected finish with nearby hardware while comparing the actual leaf thickness, screw pattern, and barrel position.

Everyday example: During a bedroom-door refresh, the installer checks that the existing hinge pockets are 3-1/2 inches high with 5/8-inch rounded corners. After confirming the screw pattern, door requirements, and hinge thickness, matching 10RH35 hinges can replace the worn fittings without assuming every similarly sized hinge is interchangeable.

Installation and Replacement Checks

Match the preparation: Compare height, open width, corner radius, leaf thickness, hole locations, and hinge backset before ordering. A 5/8-inch-radius hinge is not the same preparation as a square-corner or 1/4-inch-radius hinge.

Check the complete door: Select the hinge type and quantity for the door's height, width, weight, frame, and frequency of use. Do not treat the 3-1/2-inch size as a universal load rating. Verify any special opening requirements before substituting a residential plain-bearing hinge for another hinge type.

Support and fasten securely: Support the door during replacement, confirm sound fastening material, and use suitable screws for the actual door and frame. Verify supplied hardware and screw length before drilling. Repair stripped holes or damaged backing rather than relying on the new hinge to correct weak attachment.

Check seating and movement: Fit both leaves to the appropriate mortise depth so the hinge seats correctly. After installation, move the door slowly through its swing and check reveal, clearances, latch alignment, and free movement. Correct binding or misalignment rather than forcing the door.

Problems It Helps Address

• Worn matching hinge hardware: Provides a replacement option when size, thickness, preparation, and application agree.
• Wrong corner shape during replacement: Clearly identifies the 5/8-inch radius for checking existing mortises.
• Mismatched visible hardware: Offers six listed finishes to coordinate with the room's fittings.

Selection and Maintenance Notes

This is not a spring-closing hinge or door-speed control. For doors fitted with closers, high-frequency service, or rated openings, confirm the required bearing type and approved hardware arrangement instead of assuming this residential model is suitable. Check fasteners, alignment, and wear during routine maintenance, and follow the manufacturer's care guidance for the selected finish.
