NEWSH35R 3.5x3.5 SPRING HINGE 1/4 RADIUS
NEWSH35R 3-1/2" x 3-1/2" Residential Spring Hinge, 1/4" Radius
Usually Ships: 1-3 Business Days
The Cal-Royal NEWSH35R 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. It measures 3-1/2" high x 3-1/2" wide when open, with a manufacturer catalog-listed .110" leaf thickness.
Practical Uses
- Residential interior doors: Add spring-assisted closing where the door's dimensions, weight, preparation, and opening requirements suit the hinge arrangement.
- Utility and storage rooms: Help return a compatible door after someone passes through carrying items.
- Replacement projects: Replace suitable 3-1/2" hinges with matching 1/4" radius mortises after checking screw spacing, 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 the complete arrangement so the door 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 3-1/2" x 3-1/2" size, 1/4" corner radius, .110" leaf thickness, mortise depth, and complete mounting pattern before ordering or cutting. NEWSH35R is not the 5/8"-radius NEWSH3558R; a shared nominal hinge size does not make their corner preparations identical.
Select the complete hinge arrangement: Consider door weight, width, height, use frequency, latch resistance, seals, 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 verify that the door swings freely. The manufacturer's guide specifies the adjustment head upward and the door closed during adjustment. Follow the 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.
Confirm fasteners: The NEWSH35R drawing identifies #10 x 1" wood screws and #10-24 x 1/2" machine screws. Match the actual supplied hardware to the door/frame material and existing threads. Drawing fastener counts do not establish the selling quantity or guaranteed package contents for this listing.
Test actual closing: Check operation from several opening positions with the actual latch and seals installed. Correct rubbing, door sag, or strike misalignment separately rather than increasing tension to overcome binding.
Problems It Helps Address
- A door routinely left open: Spring action 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: A model-specific drawing helps compare mortises and fastener positions before modifying the opening.
Closing assistance, not hydraulic control: A spring hinge does not provide a door closer's separate speed and latch controls and is not a door stop. It does not by itself guarantee positive latching, acceptable opening force, or fire-door suitability. Verify any special opening requirements and the approved complete configuration.
