E-Mag Door Closer Size 5 Square

In demanding environments like hospital surgical suites, industrial warehouses, and grand commercial lobbies, standard closers often fail to overcome heavy air pressure or thick intumescent smoke seals. A Size 5 E Mag Door Closer  bridges this gap, offering the “grunt” needed to secure heavy partitions while maintaining the accessibility of an electromagnetic hold-open system.

Why Size 5 is Critical for Heavy-Duty Specs

• Superior Closing Torque: Engineered to pull wide or heavy-gauge steel and solid timber doors into the frame, ensuring a positive latch every time the fire alarm is triggered.

• Fail-Safe Release: Wired directly to the 24V DC fire alarm circuit, the magnet releases instantly during an emergency, allowing the high-tension spring to seal the door against heat and smoke.

• Accessibility Compliance: By holding these heavy doors open during normal operation, you remove a significant physical barrier for people with disabilities, the elderly, or staff moving heavy equipment.

• Architectural Durability: These units feature reinforced high-tensile steel arms and cast-aluminum bodies designed to withstand the massive kinetic energy generated by 100kg door leaves.

Technical Specification Overview of Size 5 E Mag Door Closer

Professional-Grade E-Mag Recommendations

For doors that require maximum power and precise calibration, the Size 5 E Mag Door Closer is the premier choice. It offers an adjustable power range up to Size 6, making it easy to set exactly at Size 5 for a perfect balance of speed and force. Its hydraulic backcheck is essential for preventing heavy doors from damaging walls when opened quickly.

The Briton 996 Series remains a staple for public sector projects. While widely used in Size 4, the heavy-duty variants are designed to meet the rigorous demands of Size 5 installations. It is highly regarded for its fail-safe reliability and straightforward integration with existing building management systems.

Installation & Maintenance Pro-Tips

1. Check Your Power Supply: Size 5 E Mag Door Closer often require a slightly higher current draw during the initial “hold” phase. Ensure your 24V power supply is rated for the total number of heavy-duty magnets on the circuit.

2. Reinforce Fixing Points: Because of the high torque, ensure the closer is mounted using sex bolts (through-bolts) rather than simple woodscrews, especially on hollow-core or composite doors.

3. Latching Speed Calibration: For heavy doors, set the latch speed to be firm but not violent. A door that is too fast can bounce off the frame, while one that is too slow may not overcome the latch bolt friction.

4. Annual Pivot Service: Given the weight involved, check the closer arm’s pivot points annually for wear. A drop of high-grade machine oil ensures the movement remains silent and fluid.
