Double Cylinder Handlesets

Double Cylinder Handlesets – Enhanced Security for Glass-Adjacent Entry Doors

Double cylinder handlesets are a secure and practical solution for entry doors with sidelights, glass panels, or interior access near the lock. Unlike single-cylinder sets, which use a thumbturn on the inside, double cylinder handlesets require a key on both sides to lock or unlock the door—making them a smart choice for deterring intruders who might attempt to reach through broken glass by simply reaching inside.

At Coastal Hardware Store, our collection of double cylinder handlesets combines superior security with exquisite design. We offer a wide range of styles and finishes from trusted brands, ensuring you find the perfect match for your home’s architectural style and your enhanced security needs.

Key Considerations When Choosing Double Cylinder Handlesets

Safety & Local Building Codes: Crucially, double cylinder handlesets require a key to unlock from both the inside and outside. While this offers superior security against forced entry, it can pose a significant safety risk in emergencies (like a fire) if a key isn't readily accessible. Ensure all occupants are aware and keys are kept in a known, accessible location. Consult your local building codes and fire regulations, as they may restrict or prohibit the use of double cylinder locks in certain residential or commercial applications.
Door Handing: Determine your door's handing (left-hand or right-hand) to ensure the handleset's lever/knob is oriented correctly. While many handlesets are reversible, some are not.
Backset & Door Prep: Measure your door's backset (distance from the door's edge to the center of the bore hole) and confirm the bore hole diameter to ensure compatibility. Most handlesets fit standard door preparations.
Finish & Style Coordination: Choose a finish and design that complements your home's existing architecture and other door hardware.
Application: Confirm if the handleset is for a front door, back door, or another entry point, as this might influence specific security features or durability needs.

Frequently Asked Questions About Double Cylinder Handlesets

Q: What is a double cylinder handleset?

A: A double cylinder handleset features a keyed deadbolt on both the exterior and interior sides of the door. This means you need a key to lock or unlock it from either side, offering extra security, especially for doors near glass or sidelights.

Q: When should I use a double cylinder handleset?

A: Use a double cylinder handleset on doors with nearby windows or glass panels, where someone could otherwise reach inside and unlock the door manually. It's also used in certain commercial or custom residential settings where enhanced security is a primary concern, and controlled egress is permissible.

Q: Are double cylinder locks allowed everywhere?

A: Not always. Some local building codes and fire safety regulations restrict or prohibit the use of double cylinder locks in certain residential settings, especially as primary exits, due to the safety concern of requiring a key for emergency egress. Always consult your local regulations or a qualified installer before making a decision.

Q: Do double cylinder handlesets come with a matching interior trim?

A: Yes, generally, a double cylinder handleset is sold as a complete unit that includes a matching interior trim (often a dummy lever or knob) to ensure a cohesive look from both sides of the door.

Q: How do I know if a handleset will fit my door?

A: To ensure proper fit, you'll need to measure your door's thickness, backset (distance from the door's edge to the center of the bore hole), and confirm the bore hole diameter to ensure compatibility. Most handlesets are designed for standard door preparations, but checking these measurements against the product specifications is crucial.
