Why Choose a Double-Sided Lock for a Frameless Glass Door?

The Frameless Double-Sided Glass Door Lock is specifically designed for situations where maximum security is required without sacrificing the open, modern aesthetic of frameless glass. In a frameless system, there is no surrounding metal to house a traditional lock, making this center-mounted solution ideal. The double-sided nature of the Frameless Double-Sided Glass Door Lock prevents a common security breach where an intruder smashes the glass and simply reaches in to turn a thumb-turn. By requiring a key from both sides, the Frameless Double-Sided Glass Door Lock ensures that the door remains impassable without authorized access, making it a superior choice for protecting sensitive areas.

How Does It Install on a Truly Frameless Door?
Installation of the Frameless Double-Sided Glass Door Lock is a precise, professional task. The lock is designed to be mounted directly through a hole drilled in the center of the tempered glass door itself. This drilling must be performed by a professional glazier before the glass is tempered or on-site with specialized equipment to prevent shattering. The lock body is inserted through this hole, and a mounting plate on the opposite side is tightened with set screws, clamping the glass securely between the components. The strike plate is then mounted onto the adjacent fixed glass panel or a minimal floor or header guide. This method allows the Frameless Double-Sided Glass Door Lock to function independently of a traditional door frame.

What Are the Fire and Safety Code Considerations?
The Frameless Double-Sided Glass Door Lock, as a double-cylinder lock, is subject to strict building and fire code regulations. Because it requires a key to exit, it can be considered a potential obstruction during an emergency evacuation. Many local codes restrict or prohibit such locks on primary egress doors in commercial and public buildings. It is absolutely essential to consult with your local building authority and a fire marshal before specifying or installing a Frameless Double-Sided Glass Door Lock. They are often permitted on specific interior rooms (like record storage or server rooms) but are generally not allowed on doors that serve as a main exit.

Can This Lock Be Integrated into a Master Key System?
Yes, a high-quality Frameless Double-Sided Glass Door Lock is designed for commercial integration. The lock typically uses a standard keyway , allowing the cylinders to be re-keyed by a professional locksmith. This means the Frameless Double-Sided Glass Door Lock can be incorporated into your building’s master key system, providing seamless access control. Authorized personnel can use a single master key for all doors, while different levels of access can be assigned with sub-master keys, making the Frameless Double-Sided Glass Door Lock a manageable and convenient part of your overall security strategy.

How Does It Compare to a Single-Sided Keyed Lock?
The fundamental difference lies in control over egress. A single-sided keyed lock has a key on the outside but a thumb-turn on the inside, allowing for free exit. The Frameless Double-Sided Glass Door Lock replaces that interior thumb-turn with a second key cylinder. This makes it significantly more secure for controlling access from inside the room, which is why it is chosen for areas containing valuables, sensitive information, or hazardous materials. The Frameless Double-Sided Glass Door Lock provides a level of security that a single-sided lock simply cannot offer.
