Union L2C26S DDA 55mm Backset 72mm C/C Euro Escape Lock Satin
Finding a door lock that effortlessly combines robust everyday security with rapid emergency egress can often feel like a compromise. The Union L2C26S DDA 55mm Backset 72mm C/C Euro Escape Lock Satin completely solves this challenge, delivering an intelligent mechanical solution designed specifically for modern commercial, residential, and institutional environments. Designed to assist building owners and facilities teams in satisfying their legal obligations under the Equality Act, this versatile mortice lock ensures that anyone inside a room can exit quickly and safely without needing to manipulate separate turn knobs or search for keys.
Crafted around standard European architectural dimensions, this mortice unit features 72mm centres and a 55mm backset, which sits smoothly inside timber doors of varying thicknesses. Whether you manage a bustling educational facility, a modern healthcare centre, a busy office complex, or a residential development, you require hardware that protects premises against unauthorised access from the outside while guaranteeing instant egress from within. The Union L2C26S provides precisely that balance. A simple, natural downward press on the interior lever handle instantly retracts both the latch and the deadbolt at the same time, granting immediate exit during an emergency.
Manufactured to exacting British and European standards, this lock features a tough black powder-coated steel casing paired with an elegant satin stainless steel forend and matching strike plate. It resists corrosion, withstands rigorous daily traffic, and integrates smoothly into contemporary interior design schemes. Doorfit is proud to supply this dependable piece of architectural hardware, giving you total peace of mind regarding compliance, durability, and user safety.

Single Action Emergency Egress
In an urgent situation, every single second counts. People should never be expected to fumble with secondary deadbolt turns or master key cylinders when trying to leave a building safely. This unit incorporates an intelligent internal escape mechanism specifically engineered to tackle this risk head on.
When someone pushes down on the inside lever handle, the internal components withdraw both the latch bolt and the extended deadbolt simultaneously. This single, fluid motion completely clears the lock from the strike plate, opening the door instantaneously. It provides intuitive protection that functions reliably even in low light or panicked environments.
Meeting Accessibility Standards
Creating barrier-free environments is both a legal mandate and an ethical commitment for property developers and facilities managers across the United Kingdom. This escape lock assists in fulfilling duties required under the Equality Act, previously known as the Disability Discrimination Act or DDA.
It fully satisfies the recommendations set out in British Standard BS8300 as well as Building Regulations Approved Document M. By reducing the physical effort needed to unlock and open doors, it accommodates individuals with limited hand strength, arthritis, or mobility impairments, making properties safe and accessible for all occupants.
Engineered for Robust Performance
The heart of this locking mechanism lies in its durable construction. UNION has built this hardware to endure relentless, heavy-duty cycling in commercial properties. Both the deadbolt and the latch bolt are formed from solid stainless steel, providing supreme resistance against physical wear, tampering, and forced entry attempts. When thrown with a single turn of an appropriate euro profile key or cylinder turn, the deadbolt extends a substantial 16mm deep into the reinforced frame strike plate, establishing a solid barrier against unwanted intrusion.
The internal follower is forged from heavy-duty 8mm zinc, crafted precisely to handle the repetitive torsional forces generated by modern commercial lever furniture. To ensure consistent daily function, the lock case is pre-pierced at 38mm centres to accept through-door fixing bolts, which securely fasten architectural rose furniture and escutcheons without relying on loose surface wood screws. This structural design prevents handles from wobbling or pulling loose over time, ensuring your access assemblies stay tidy and rigid.
Because operational ease is paramount, the lock includes an easily reversible stainless steel latch bolt and escape mechanism. Installers do not need to disassemble complex spring cassettes or risk dislodging interior parts on site. Timber doors hinged on either the left or the right can be fitted with the same versatile unit, drastically cutting down installation time and eliminating costly ordering mistakes on extensive refurbishment projects.
Fire Door Assessment and Compliance
Internal fire doors are essential life safety assets in every commercial building. Hardware fitted to fire doors must preserve the integrity of the door assembly without failing prematurely during a fire event. This mortice lock has been thoroughly assessed under EN 1634-1 testing standards.
It is fully certified for use on both 30-minute and 60-minute timber fire doors when installed alongside appropriate intumescent protection packs. Holding an official EC Certificate under number 0832-CPD-6046, it meets stringent BS EN 12209 standards and carries valid CE marking for complete building control peace of mind.
Smart Modular Design
Standardisation across commercial doors makes life far easier for joiners, carpenters, and facility caretakers. The modular case profile follows universal European dimensions, ensuring that timber mortice prep work remains uniform throughout your entire building project.
The casing accepts virtually any standard euro profile cylinder, allowing you to incorporate master key suites, key-and-turn cylinders, or construction keying arrangements seamlessly. Supplied with an essential split spindle, it allows independent movement between internal and external lever handles right out of the box.

Installation Advice and Handle Selection
To achieve optimal safety and smooth operation from your lock setup, correct hardware pairing is essential. The Union L2C26S DDA 55mm Backset 72mm C/C Euro Escape Lock Satin must always be fitted with sprung bolt-through lever handles. Because the internal escape mechanism simultaneously drives both the latch and the deadbolt back into the casing, it demands adequate spring return strength from the door furniture to reset effortlessly after each use.
The lock comes equipped with a dedicated split spindle. When installing, ensure that the split spindle is aligned correctly with the inside escape side of your door leaf. This arrangement guarantees that the exterior lever only operates the latch bolt when unlocked, while the interior lever retains full control over the emergency egress action at all times. Always verify that your door hinges are square and true, which prevents lateral pressure from binding the latch against the satin strike plate.
Routine maintenance remains straightforward. Inspect the latch and strike surfaces periodically, keep the interior follower free of debris, and check that fixing screws on the faceplate remain snug. Backed by a full five year manufacturer guarantee from UNION, this escape lock provides exceptional long-term value and rock-solid reliability for your estate.
