Multi-point locks

OMR expansion locks are an effective technical solution for securely locking hinged doors, sliding doors, and drawers in industrial furniture and professional furnishings. Designed to provide multipoint restraint, they are ideal in applications requiring greater stability and strength, such as technical cabinets, workstations, storage systems or workshop equipment. Available in horizontal and vertical versions, they offer broad compatibility with wood and wood-derived panels. Variants include deadbolt or cremone bolt mechanisms with translating rods, chrome, galvanized or nickel-plated finishes, and sturdy materials such as steel and die-cast metal.

Expansion locks are considered an alternative to the more popular locks with rotating rods and are ideal for installation on medium-high sashes: their features, in fact, allow them to strengthen the lock on the ends.

These locks, also called cremone locks or crémone bolt locks, are a first choice for applications where it is necessary to recreate not a single locking point but two or three.

Expansion locks find a variety of applications: they are very popular for office furniture with double hinged doors, for technical equipment for professional settings such as workshops and industries, for folding grilles, not to mention their massive use in pool tables and foosball tables.

OMR Locks provides expansion locks to customers with very different needs and is able to guarantee not only excellent quality but also endless customization possibilities.

FOCUS

To choose the right expansion lock, check the type of door (hinged or sliding) and the need for multipoint locks. Cremone bolt versions with translating rods are suitable for tall sashes. Models are easily installed with screw fastening on MDF or HPL panels. The choice of keyed alike (single KA, mixed KD or passe-partout) allows security to be adapted to the needs of the environment. Available lengths range from 15 to 35 mm, while the most common hole diameters are 17 and 23 mm.

FAQ

What are typical applications of expansion locks?

Expansion locks are mainly used on industrial double door furniture, technical cabinets, workshop furniture, professional tables, and devices with medium-high doors that require multi-point distributed locking.

What is the difference between an expansion lock with espagnolette and one with deadbolt?

The espagnolette version uses translating rods to achieve multipoint locking on multiple sides of the door, ideal for tall doors. The deadbolt version, on the other hand, closes in a single point and is more suitable for smaller compartments.

Can I install an expansion lock on MDF or HPL panels?

Yes, OMR expansion locks are designed to be installed on wood-derived materials such as MDF and HPL by screw fastening. It is important to check the thickness of the panel and choose the appropriate length of the lock.
