Half-Mortise Light Duty Self-Closing Spring Hinges
Only one cutout (mortise) is needed for these hinges—the offset design allows surface mounting the door leaf and mortise mounting the frame leaf. These hinges are often used when it is difficult to mortise the frame, such as when hanging a hollow door on a solid frame. They are also good for lightweight screen and storm doors as well as small gates. Springs in these hinges automatically swing doors and gates closed behind you. To adjust the closing tension, use the included tension adjustment tool. All hinges have a nonremovable pin to deter tampering.
Brass-plated low-carbon steel hinge has more corrosion resistance than painted and primed low-carbon steel.

Plastic Clean Room Hinges
Keep environments free of contaminants—with plastic hinge leaves and a metal pin, there's no metal-to-metal contact that can release particles as hinges open and close. The hinge pin is nonremovable to deter tampering.
