Reliable Architectural Security with the Union L2241 Oval Sashlock 76mm Polished Brass
Choosing dependable locking hardware for commercial timber doors and busy domestic entrances often presents a tricky balance between solid security, smooth day-to-day operation, and refined visual appeal. Traditional mortice locks without modular cylinder bodies can leave facilities managers and property owners limited in keying options, especially when standardising systems across a broad premises. The Union L2241 Oval Sashlock 76mm Polished Brass solves these daily operational challenges by combining a robust mechanical sashlock case with the versatility of an oval profile cylinder system.
Engineered by one of the most trusted names in British security engineering, this mortice sashlock provides dependable latching during normal working hours and deadlocking when the premises is vacated. The 76mm case depth, which creates a comfortable 57mm backset, allows ample knuckle clearance from the door frame while seating neatly within standard UK joinery preparations. When retrofitting existing timber doors or outfitting new fire-rated assemblies, the lock integrates smoothly into demanding building environments.
Beyond basic access control, this model is built to stand up against physical intrusion attempts while maintaining full compliance with modern timber fire door standards. Featuring hardened steel anti-saw rollers inside the brass deadbolt and assessment for 60-minute timber fire assemblies under EN 1634-1, the Union L2241 delivers a robust hardware foundation that trade professionals and property owners can install with absolute confidence.
Step by Step Engineering and Operation Highlights
Stage 1 Hardened Anti-Saw Deadbolt Protection
The locking mechanism utilises a solid brass deadbolt equipped with free-spinning hardened steel rollers. If an intruder attempts to cut through the bolt with a hacksaw, the loose internal steel rollers spin freely against the blade teeth, preventing physical sawing attacks and securing your property.
Stage 2 Fully Reversible Latch Handing
Designed for quick joinery fitting, the solid brass latch bolt reverses easily without needing you to dismantle the main lock case. This flexible feature accommodates both left-handed and right-handed timber doors effortlessly, cutting down installation time and removing the risk of loose internal springs on site.
Stage 3 Bolt-Through Lever Fixing Points
Modern architectural lever handles require secure bolt-through fixings to prevent handles from pulling away from the door over time. The lock case is pre-pierced with dedicated holes that allow through-door tie bolts to pass directly through the body without jamming the internal springing mechanisms.
Stage 4 Oval Cylinder Mechanical Control
Operating with an oval profile cylinder, the lock accepts either a double cylinder key setup or a cylinder with internal thumbturn. The smooth internal cam mechanism throws the deadbolt a full 12mm into the steel frame keep with an exact, positive mechanical movement on every turn.

Installation and Maintenance Advice
To maintain smooth latch action, ensure the door frame striking plate aligns cleanly with the latch bolt bevel without rubbing against the frame timber. When installing on designated fire check doors, always install suitable approved intumescent lock jackets around the lock case and behind the forend to preserve fire compartment integrity. Never spray heavy oil inside the lock mechanism, and use a dry graphite lubricant if the cylinder or follower requires routine maintenance.
