E-Mag Door Closer Size 6 Square

While a standard office door typically uses a Size 3 or 4, a Size 6 E Mag Door Closer is a professional-grade specification for extreme applications. These are the “industrial workhorses” found in:

• Hospital Trauma Centers: Where wide double doors must stay open for bed movement but seal instantly during an alarm.

• Airport Hangars & Terminals: To combat high air-pressure differentials and heavy wind loads on exterior-facing fire exits.

• Theaters & Stage Doors: Where heavy, sound-attenuating doors require significant force to close.

• Industrial Warehouses: To manage heavy steel-clad doors that provide high-duration fire protection.

Why Size 6 is the Essential Heavy-Duty Specification

1. High-Torque Closing Force

Size 6 E Mag Door Closer  provide the massive hydraulic “grunt” required to overcome thick intumescent smoke seals and air pressure (the “chimney effect”) that often prevents lighter doors from latching. It ensures the door doesn’t just close, but positively latches, maintaining the integrity of the fire compartment.

2. Accessibility without Effort

The E-Mag functionality is vital for Equality Act (ADA) compliance on heavy doors. By holding a 120kg door open during normal hours, you remove a significant physical barrier. The Swing-Free mode is particularly useful, allowing the door to be moved with zero resistance, as if no closer were attached at all, until the fire alarm triggers the safety closure.

3. Fail-Safe Electronic Integration

Wired directly into the building’s 24V DC fire alarm system, these units are designed to be fail-safe. In the event of a fire, a power cut, or a system test, the electromagnet releases instantly. The pre-tensioned Size 6 mechanical spring then takes over, securing the door in seconds.

Professional-Grade E-Mag Recommendations

For doors that demand the highest level of architectural control, the Size 6 E Mag Door Closer is the premier choice. It is power-adjustable up to Size 6 and features an integrated electro-mechanical hold-open. Its adjustable backcheck is a critical safety feature for heavy doors, acting as a hydraulic shock absorber to prevent the door leaf from damaging walls or hinges when opened with force.

The Briton 996 Series is a legendary name in the fire safety industry. The heavy-duty variants of this Size 6 E Mag Door Closer are built for long-term endurance in public infrastructure projects. Known for its “swing-free” or “hold-open” versatility, it is a staple in healthcare settings where large ward doors must be managed with absolute reliability.

Installation & Safety Maintenance Pro-Tips

• Reinforced Mounting: For a Size 6 installation, standard woodscrews are rarely sufficient. Always use through-bolts (sex bolts) to ensure the Size 6 E Mag Door Closer body is anchored securely through the door leaf to prevent it from tearing out under high spring tension.

• Hinge Compatibility: Ensure your hinges are Grade 13 or 14 (rated for 120kg+). A Size 6 closer will put significant stress on the top hinge; using high-quality ball-bearing hinges is mandatory.

• Circuit Load Check: Size 6 solenoids can have a higher current draw. Ensure your 24V power supply is robust enough to handle the “hold” current for multiple heavy-duty units on a single circuit.

• Quarterly Calibration: Given the weight involved, check the latch speed every three months. Changes in building temperature can affect the hydraulic oil density, which may require a minor valve adjustment to ensure the door still latches perfectly.
