Latch Protectors
Frequently Asked Questions
What is a latch protector?
A latch protector (latch guard) is a steel plate mounted on the exterior side of the door to shield the latchbolt from tampering. Unlike wrap plates, which reinforce the lock bore, latch protectors specifically defend against forced-entry attempts. At National Lock Supply, we supply latch protectors for residential, commercial, and storefront doors.
Why are latch protectors important?
They provide an extra layer of protection against prying, shimming, or “loiding” attacks where intruders try to bypass the latch. This makes them a common upgrade for aluminum storefronts and hollow metal doors.
What types of doors accept latch protectors?
They can be installed on wood, hollow metal, and aluminum storefront doors with cylindrical or mortise locks. Special models exist for outswing glass doors.
How do latch protectors compare to wrap plates?
Latch protectors guard the strike side of the latch, while wrap plates reinforce the lock body and bore hole. Many facilities use both together for maximum security.
What finishes are available?
Latch guards are available in Stainless Steel, Aluminum, and Dark Bronze, matching most commercial storefront finishes.
Do latch protectors interfere with key operation?
No. They are designed with cutouts or spacers to allow full key access to the cylinder while blocking pry tools.
Are latch protectors ADA compliant?
Yes, when installed flush and clear of lever handles or thumbturns.
Are latch protectors UL listed?
Some models are UL-certified for use on fire-rated openings, ensuring compliance where fire doors are required.
Can latch protectors be used with deadbolts?
Yes, latch protectors are made for cylindrical lock latches, mortise locks, and deadbolts, depending on the model.
Why buy latch protectors from National Lock Supply?
We carry heavy-duty latch protectors in multiple finishes, with models for storefronts, hollow metal, and wood doors, ensuring upgraded security without replacing existing locks.
