EL-B500U Electric Bolt Lock for Fully Frameless Glass Door – Fail Safe
EL-B500U Electric Bolt for Fully Frameless Glass Door – Fail Safe Type is a specialized electric bolt lock designed for fully frameless glass doors. It provides reliable electronic access control with configurable 0, 3, 6, or 9-second operation delay, making it suitable for offices, commercial buildings, access-controlled entrances, and other glass-door security applications.
Description
The EL-B500U is an electric bolt lock specifically designed for fully frameless glass door installations. It is part of the Elock bolt-action lock range and is intended for integration with electronic access-control systems.
Its fail-safe configuration is designed so that the lock releases when power is removed, making it appropriate for applications where controlled release during a power failure is an important safety consideration. The lock also provides selectable operation-delay settings of 0, 3, 6, and 9 seconds, offering flexibility for different access-control requirements.
Key Features
- Model: EL-B500U
- Product Type: Electric Bolt / Bolt Action Lock
- Lock Type: Fail Safe
- Designed for: Fully frameless glass doors
- Operation Delay: 0 / 3 / 6 / 9 seconds
- Electronic access-control operation

- Suitable for commercial and professional security installations
Designed for Fully Frameless Glass Doors
The EL-B500U is specifically listed as being suitable for fully frameless glass doors, making it a purpose-built option for modern glass entrances where conventional framed-door locks may not be appropriate.
Its design is particularly suited to installations where maintaining the clean appearance of a frameless glass entrance is important while still providing electronically controlled locking.
Fail-Safe Operation
The fail-safe design is intended to release the locking mechanism when electrical power is removed. This characteristic can be valuable for access-control installations where emergency egress and controlled unlocking during a power interruption are priorities.
Because fail-safe operation affects building security and life-safety behavior, the lock should be installed and configured according to the requirements of the specific access-control system and applicable local safety regulations.
Adjustable Operation Delay
The EL-B500U supports selectable delay settings of:
- 0 seconds
- 3 seconds
- 6 seconds
- 9 seconds
This allows installers to configure the lock’s operating behavior according to the requirements of the access-control system.
Electronic Access Control Integration
The electric bolt can be incorporated into an electronic door-access system and controlled through compatible access-control equipment.
Typical system components may include:
- Access-control controllers
- RFID/card readers
- Keypads
- Biometric readers
- Exit buttons
- Door-access management systems
- Compatible power supplies
This makes the EL-B500U suitable for controlled entrances in commercial and institutional environments.
Suitable Applications
The EL-B500U can be used in a variety of professional access-control installations, including:
Corporate Offices
Secure frameless glass entrances while maintaining a modern appearance.
