NEWSH44R 4x4 SPRING HINGE 1/4 RADIUS CORNERS
NEWSH44R 4" x 4" Residential Spring Hinge, 1/4" Radius Corners
Usually Ships: 1-3 Days
The Cal-Royal NEWSH44R is a single-acting, full-mortise residential spring hinge with 1/4" radius corners. Its adjustable spring action helps return a compatible swinging door toward the closed position. The hinge measures 4" high x 4" wide when open, with a manufacturer-listed .110" leaf thickness.
Practical Uses
- Residential interior doors: Add spring-assisted closing where the complete hinge arrangement suits the door's size, weight, and opening requirements.
- Utility and storage rooms: Help return a compatible door after someone passes through carrying items.
- Replacement projects: Replace suitable 4" hinges with matching 1/4" radius mortises after checking hole positions, leaf thickness, and barrel clearance.
Everyday example: After carrying laundry into a utility room, the adjusted spring hinges help bring the door back toward the frame. The installer checks that the complete arrangement closes and latches reliably without unnecessary opening effort.
Installation and Adjustment
Match the preparation: Full-mortise installation recesses one leaf into the door and the other into the frame. Verify the 4" x 4" size, 1/4" corner radius, .110" leaf thickness, mortise depth, and full mounting pattern before ordering or cutting. NEWSH44R is not the 5/8"-radius NEWSH4458R; the same nominal size does not make their corner preparations identical.
Select the complete hinge arrangement: Consider door weight, width, height, use frequency, seals, latch resistance, and air pressure. The manufacturer advises ball-bearing or concealed-bearing hinges when combining ordinary support hinges with spring hinges. Do not assume one spring hinge will close every door or that this residential model substitutes for heavy-duty commercial hardware.
Install before tensioning: Align hinge axes and check that the door swings freely. The manufacturer's guide specifies the adjustment head upward and the door closed during adjustment. Follow its illustrated tension-adjusting rod and set-pin procedure, keeping the loaded mechanism controlled. Test after each adjustment and observe the limits supplied with the hardware.
Verify fasteners: The model references identify #10 x 1" wood screws and 12-24 x 1/2" machine screws; the specification sheet calls for a #10 head on the machine screws. Match the actual supplied screws to the frame threads and countersinks. Drawing counts do not establish a guaranteed per-hinge package quantity.
Test actual conditions: Check closing and latching from several opening positions with the actual latch and seals installed. Correct rubbing, door sag, or strike misalignment separately rather than increasing spring tension to overcome binding.
Problems It Helps Address
- A door routinely left open: Spring force assists return toward closed on a properly fitted opening.
- Closing force that needs refinement: Adjustable tension helps the installer tune the hinge arrangement.
- Replacement uncertainty: Model-specific preparation references help compare mounting details before altering the door or frame.
Closing assistance, not hydraulic control: Spring hinges do not provide a door closer's separate speed and latch controls and are not door stops. The hinge alone does not guarantee positive latching, acceptable opening force, or suitability for a labeled fire-door assembly. Verify any special opening requirements and the approved complete configuration.
