Seco-Larm DH-171SQ Flush-Mount Magnetic Door Holder
The Seco-Larm DH-171SQ is a flush-mount magnetic door holder designed to work with Seco-Larm door closers. It provides a reliable 33 pounds (15 kg) of holding force and features a fail-safe design that releases when power is cut. Its compact profile makes it suitable for space-constrained installations, while its compatibility with wired power ensures stable operation in commercial environments.
Seco-Larm DH-151SQ Surface-Mount Magnetic Door Holder
The DH-151SQ provides a 33 lb (15 kg) holding force in a surface-mount configuration. This model is designed to work with Seco-Larm door closers to control release and closing, offering a reliable fail-safe operation with no residual magnetism, which aids in easy door release during emergencies or power loss.
Seco-Larm DH-171SQ Pack Of 2 Flush-Mount Magnetic Door Holders
This pack includes two flush-mount holders that deliver consistent 33 lb (15 kg) holding force per unit. The 3-volt-compatible tri-volt functionality supports 12/24 VAC/VDC and 120 VAC, making the set highly adaptable for varying installation requirements. The aluminum faceplates offer durability and a low-profile appearance for commercial spaces.
MAG-Mate D3X1BLP Magnetic Door Holder With Plate
The MAG-Mate D3X1BLP combines a powerful rare earth magnet with a non-marring rubber housing. It holds up to 27 lb and includes a plate for mounting, suitable for indoor and outdoor applications as a door stopper and holder. Its durable construction and weather-tolerant materials make it versatile for residences, offices, garages, RVs, and marine environments.
QWORK Electric Magnetic Lock
The QWORK model offers a significantly higher holding force of 60 kg (130 lbs) and is designed for door access control systems. It operates in NC (normally closed) mode, meaning the door remains locked when power is supplied. With a voltage spike suppressor built-in, this magnet provides a robust security solution for high-traffic entrances, and its compact form fits standard frame assemblies. Installation involves mounting under the top of the door frame for reliable closure.
Electro Magnetic Door Holder MDH102 Aluminum/Duro
MDH102 is a basic door holder with a 50 kg (approximately 110 lb) holding force and dual voltage capability (12/24V). It provides a straightforward option for users requiring strong magnetic retention with a simple power setup, suitable for light to moderate commercial usage and high-traffic doors where reliability is essential.
Buying Guide: Key Considerations For Choosing An Electro Magnetic Door Holder
- Holding force: Match the magnet strength to door weight and use case. Heavier doors and high-traffic areas typically require 33 lb (15 kg) or more per unit, while lighter interior doors may be adequately served by lower figures.
- Mounting style: Flush-mount units offer a sleek profile, while surface-mount options can simplify installation and accessibility. Some packs provide multiple units for larger openings.
- Voltage and power options: Consider tri-volt compatibility (12/24 VAC/VDC) and single-voltage models. Ensure your power supply aligns with the device’s requirements and your building’s electrical standards.
- Fail-safe vs. fail-secure: Fail-safe magnets release when power is cut, benefiting emergency egress. Fail-secure designs remain locked when powered, typically used where continuous access control is needed.
- Durability and materials: Aluminum faceplates and rugged housings improve longevity in busy environments. Non-marring rubber housings protect doors and frames.
- Installation context: For commercial spaces with Seco-Larm closers, choose compatible models or packs to simplify wiring and alignment with existing hardware.
- Redundancy: In high-traffic buildings, consider packs (two units) to cover wide door openings, ensuring consistent holding force across the entire door width.
- Maintenance: Look for units with clear residual magnetism properties and simple release mechanisms to reduce maintenance downtime.
When selecting an electro magnetic door holder, assess the door’s weight, frame material, and the desired release behavior. Use the buying guide as a starting point, and verify compatibility with any existing door closers or access control systems to ensure a secure and compliant installation.
