A Euro mortise lock is a precision-engineered locking mechanism that is installed within a rectangular pocket (mortise) cut into the edge of a door. Designed according to European DIN and EN standards, these locks feature a standard Euro-profile cylinder keyway and are widely used in both residential and commercial projects across Europe and internationally.
Compared to ANSI mortise locks, European mortise locks have narrower faceplates, different installation cutouts, and are typically paired with European-style lever handles. They offer excellent compatibility, design uniformity, and enhanced security in a more compact form factor.

What is a Euro mortise lock?
A Euro mortise lock is a precision-engineered lock mechanism installed within the edge (mortise pocket) of a door. Designed to European DIN and EN standards, it features a standard Euro-profile cylinder keyway, narrower faceplate compared to ANSI locks, and is compatible with European-style lever handles. It is widely used in commercial and residential projects for its superior security, durability, and design uniformity.
D&D Hardware Euro mortise locks are tested and certified according to BS EN 12209 and EN 1634. They carry CE marking with a fire rating of up to 260 minutes. The CE classification is 3X910G3BC20. All products comply with DIN 18251 dimensional standards, ensuring compatibility with standard European door preparations.
Mortise locks are installed inside a rectangular pocket cut into the door edge, offering superior strength, security, and a wider variety of functions such as deadbolt, latch, and privacy options. They are ideal for commercial and high-traffic applications. Cylindrical locks are surface-mounted through a bored hole and are simpler to install but provide less security and fewer function options, making them more suitable for light-duty residential use.
Yes. D&D Hardware Euro mortise locks are tested and certified to EN 1634 fire resistance standards, achieving up to 260 minutes (4+ hours) of fire rating. They are suitable for use on fire-rated metal and wooden doors in commercial buildings, hospitals, hotels, and other safety-critical environments where fire door compliance is required.
D&D Hardware offers a comprehensive range including: CE EN12209 certified sash locks (entry function), deadbolt locks (storeroom function), latch bolt passage locks, night latch locks, emergency exit locks (EN179 compliant), bathroom/privacy locks, sliding door hook bolt locks, and narrow stile locks for aluminium and glass door systems. All are available in stainless steel 304 with multiple backset options.
D&D Hardware mortise locks feature forend plates and strike plates made of stainless steel 304 (SUS304). Latch bolts and deadbolts are also constructed from SUS304 stainless steel for maximum corrosion resistance and durability. The lock cases are zinc-plated for additional protection. For narrow stile locks, both SUS304 stainless steel and brass options are available to suit different aesthetic requirements.
Consider the following factors: door type (wooden, metal, aluminium), door thickness, required function (entry, privacy, emergency exit, passage), fire rating requirements, backset size, and cylinder type. For narrow profile doors such as aluminium storefronts, choose our narrow stile range. For sliding doors, select our hook bolt locks.
