Mortice Locks
Union HD72SL S DDA 60mm Backset Euro Sashlock Satin
High traffic environments require hardware that maintains consistent performance regardless of how frequently it is operated throughout the day. This Union sashlock provides a reliable solution for public buildings where users may not always handle door furniture with the same level of care, which helps protect your investment in premises infrastructure. Because this unit is engineered to meet strict accessibility standards, it simplifies the process of creating inclusive environments for everyone within your facility.
The satin stainless steel finish offers a clean appearance that fits well in modern commercial spaces while providing the necessary corrosion resistance for busy areas. You receive a product that has undergone rigorous endurance testing to ensure it functions smoothly for years, which reduces the frequency of your maintenance visits and keeps internal doors operating at their absolute best.

Why Choose the Union HD72SL S DDA 60mm Backset Euro Sashlock Satin
This hardware solution prioritises long term mechanical integrity and ease of use in heavy traffic commercial zones.
Exceptional Mechanical Lifecycle
Engineers have successfully tested this lock to three and a half million cycles which vastly exceeds standard industry requirements for mortice hardware. This performance ensures that you avoid premature failure in busy office or public corridors where the latch and deadbolt see constant daily activity from a wide variety of different users.
Standardised Architectural Footprint
The design team developed this range with a common footprint to allow for simple upgrades and replacements across your existing estate. Because the case sizes remain consistent across the HD72 series, your maintenance team can replace older units without needing to modify the door timber or alter existing furniture configurations on site.
Inclusive DDA Accessibility
Design features are aligned with the Equality Act requirements to assist facility managers in meeting their legal obligations for public building access. The 72mm centre measurement provides plenty of space for user friendly handle operation, which helps people with limited dexterity move through your premises with greater ease during their daily routines.
Quick Reversible Handing
Site installation becomes faster because the latch mechanism allows for quick adjustment without complex tools. You can easily adapt the orientation to suit doors hinged on either the left or the right side, which saves significant time when you are managing large scale door installation projects in new builds or refurbishments.
Integrated Splinter Guard
Professional aesthetics are maintained through the inclusion of a factory fitted splinter guard which creates a clean finish around the faceplate. This small detail prevents the splintering of timber during the initial fitting process and ensures that every door looks neatly finished while also protecting the surrounding woodwork from long term wear.
Rattle Reduction Technology
The inclusion of a specialised spindle grip feature helps prevent the annoying rattle often associated with high use door hardware. By keeping the spindle and handle firmly in place, the lock maintains a quiet and solid feeling every time a user operates the door, which contributes to a more pleasant environment for everyone inside.
Engineering Quality and Daily Performance
Precision components combine with high grade materials to deliver a lock that survives the daily grind of commercial use.
Internal Mechanism and Force Distribution
Inside the mild steel case, the internal springs and follower are designed to distribute force evenly across the contact points. This level of internal geometry reduces friction and prevents the wear patterns that typically lead to a drooping handle or a stuck latch bolt over many years of service.
The deadbolt is crafted from high strength steel and chrome plated to provide high levels of resistance against physical force. Because the mechanism uses smooth action components, the key turn feels consistent even after thousands of operations, which provides users with a sense of quality each time they secure their room or office space.
Weather Resistance and Long Term Finish
The forend and strike plate are manufactured from grade 304 stainless steel to prevent rust and surface corrosion in high traffic settings. This material is chosen because it keeps its silver aesthetic even in environments where cleaners are frequently used or where humidity levels might fluctuate within a building throughout the changing seasons.
By using stainless steel instead of cheaper plated alloys, the lock maintains its integrity against scratches and minor impacts that occur in public hallways. Your doors will continue to look well maintained over time because the satin finish hides minor marks well while staying resistant to the environmental factors that often degrade cheaper hardware solutions.
Installation and Operational Workflow
Effective installation involves accurate preparation of the door mortice and proper alignment of the strike plate.
1
Preparing the Mortice
Start by measuring the case depth and height to ensure your mortice is clean and square before inserting the lock body. Use a sharp chisel to remove any loose debris from the cavity because this allows the unit to sit perfectly flush against the door edge for a clean professional installation.
2
Handing and Final Fixing
Adjust the latch orientation if necessary for your specific door swing by reversing the bolt mechanism before you secure the lock to the door. Once you verify the latch direction, fix the unit using the supplied screws through the pre-drilled holes to ensure it is held firmly in place during daily operation.
3
Strike Plate Alignment
Fix the strike plate to the door frame with precise attention to the gap between the door and the frame. Use the adjustable strike features to ensure the latch engages perfectly without needing excessive force, which keeps the door operating smoothly and prevents unnecessary impact on the strike plate over time.
Expert Installation and Care Tip
When you fix the door furniture, ensure that you do not overtighten the through bolts as this can bind the internal mechanism and lead to sluggish handle movement. A simple clean with a dry soft cloth will keep the satin stainless steel finish looking like new for many years without the need for harsh chemical cleaners.
