Key Features of Union Door Closers

Union door closers incorporate rack and pinion mechanism technology, providing superior durability compared to cam-action alternatives whilst delivering smooth, controlled closing action throughout the door's swing arc. This proven technology ensures consistent performance across the product's service life, with minimal degradation in closing force or speed adjustment accuracy. Variable power sizing across the range accommodates doors from lightweight internal fire doors through to heavy external entrance doors up to 1400mm wide.

Adjustability represents a key strength of Union closers, with independent closing speed and latching action controls allowing precise tuning to match door weight, width and environmental conditions. Backcheck functionality on selected models prevents violent opening, protecting walls, door furniture and the closer itself from damage in high-traffic or windy locations. Many Union closers feature delayed action options, particularly valuable in healthcare and care home settings where additional door-open time assists users with limited mobility.

Installation versatility is designed into Union door closers, with reversible bodies allowing fitting to either pull or push sides of doors, and parallel arm, top jamb and transom mounting options providing solutions for various architectural constraints. Durable finishes including silver, white, gold and dark bronze enable aesthetic coordination with surrounding ironmongery whilst providing corrosion resistance in demanding environments. Union's attention to certification ensures models are available with CE marking and third-party fire door closer certification where required for regulatory compliance.

Popular Union Door Closers

Union's overhead door closer range forms the backbone of their offering, with surface-mounted models suitable for the majority of commercial and residential applications. These units typically provide size EN 2-5 power adjustment, covering doors from 40kg to 100kg and widths up to 1100mm. The standard overhead closer range features robust cast iron or aluminium alloy bodies with adjustable closing and latching speeds, suitable for both fire door and non-fire door applications when specified correctly.

For applications where aesthetics demand concealment, Union's concealed door closers provide hidden installation within the door leaf and frame, maintaining clean sightlines whilst delivering comparable performance to surface-mounted alternatives. These units are particularly popular in contemporary commercial interiors and high-end residential projects where visible door furniture is minimised. Union also offers transom-mounted closers for frameless glass door applications and situations where head-frame fixing is impractical.

The Union range extends to specialist applications including free-swing closers for disabled access routes, allowing manual positioning of doors at any angle whilst automatically closing from approximately 70 degrees. Hold-open models with electromagnetic or mechanical release provide convenient traffic management in normal use whilst ensuring automatic closure on fire alarm activation, meeting the requirements of BS 5839 fire detection and alarm systems.

Safety and Compliance

Union door closers are manufactured to comply with BS EN 1154, the British and European standard governing the performance and safety requirements for controlled door closing devices. This certification ensures closers meet defined criteria for closing force, durability (minimum 500,000 test cycles), corrosion resistance and operational safety. When specified for fire door applications, Union closers carry appropriate third-party certification confirming suitability for use on fire-resisting door assemblies tested to BS 476 or BS EN 1634 standards.

For applications involving disabled access routes, Union offers closers compliant with Approved Document M of the Building Regulations, limiting the opening force required to levels manageable by users with reduced strength or dexterity. Correct specification and adjustment of door closers is essential to balance fire safety requirements (ensuring doors close fully and latch) with accessibility needs (avoiding excessive opening resistance). The adjustability built into Union closers facilitates achieving this balance whilst maintaining compliance with both fire safety and equality legislation.

Regular inspection and maintenance of door closers is recommended to ensure continued safe operation and regulatory compliance. Building owners and responsible persons should implement inspection regimes in line with fire door inspection guidance, checking that closers fully close and latch doors from any angle without requiring excessive force. Union's robust construction minimises maintenance requirements, but periodic checking of mounting screws, arm connections and adjustment settings helps identify wear before performance is compromised.

Frequently Asked Questions

What door sizes do Union door closers suit?

Union door closers are available in various power sizes conforming to BS EN 1154 classification. Standard models typically cover EN 2-5, suitable for doors from 750mm to 1100mm wide and weighing 40kg to 100kg. Specific model selection depends on door dimensions, weight, usage frequency and whether the door is sheltered or exposed to wind pressure. Union's technical specifications provide detailed sizing guidance to ensure correct closer selection for optimal performance and longevity.

Can Union door closers be fitted to fire doors?

Yes, Union manufactures door closers specifically certified for fire door applications. When specifying closers for fire doors, it's essential to select models that carry appropriate third-party certification and are fitted according to the fire door manufacturer's specifications. The closer must be capable of closing the door fully from any angle to maintain the door's fire-resisting integrity. Union provides clear documentation identifying which models are suitable for fire door use and the maximum door sizes and weights they can effectively control in fire-rated applications.

How do I adjust a Union door closer?

Union door closers typically feature adjustment valves accessible via small screws on the closer body. These control closing speed (the main sweep from open to approximately 15 degrees from closed) and latching speed (the final movement into the closed position). Adjustments should be made gradually using appropriate screwdrivers, turning clockwise to slow the action and anticlockwise to speed it up. Avoid removing adjustment screws completely as this will release the hydraulic fluid. Models with backcheck feature an additional adjustment controlling resistance to violent opening. Consult the specific product installation instructions for detailed adjustment procedures.

Are Union door closers suitable for external doors?

Union offers door closers suitable for external applications, though model selection must account for exposure to weather, temperature variations and potentially higher wind loads. External-grade closers incorporate enhanced sealing to prevent hydraulic fluid degradation and corrosion-resistant finishes for extended service life. Door width, weight and exposure level determine the appropriate closer size – external doors generally require higher power ratings than equivalent internal doors. For particularly exposed locations, consider models with backcheck to prevent wind damage and ensure the closer is mounted on the sheltered side where possible.

What's the difference between Union's concealed and surface-mounted closers?

Surface-mounted Union door closers are fitted to the face of the door and frame, providing straightforward installation and easy adjustment access. They're suitable for the vast majority of applications and offer excellent value. Concealed closers are recessed into pockets machined into the door leaf and frame, providing invisible operation that maintains clean architectural lines. Whilst more expensive and requiring more complex installation, concealed closers are preferred for high-specification projects where aesthetics are paramount. Both types provide comparable closing performance when correctly specified and installed, with choice primarily driven by aesthetic requirements and budget considerations.
