GU SECURY multi-point locks

Exterior doors present special challenges with regard to burglar resistance, fire protection, tightness and accessibility. The GU SECURY multi-point locks more than meet these ambitious expectations. With additional locking elements in the upper and lower door area as well as individual solutions for all kinds of installation situations. With automatic locking systems, the mechanical self-locking replaces the manual locking with the key.

With GU SECURY multi-point door locks you receive a security system customised to your individual entrance situation, regardless of whether it is for timber, PVC, aluminium, steel, facade, outside or interior doors.

Locking types – self-locking

Automatic latchbolt

The convenient locking system GU SECURY Automatic, e.g. for main and apartment entrance doors. As soon as the door is shut, the Automatic latchbolts automatically throw 20 mm and are secured to prevent them being forced back – the door is locked when just pulled shut. These locking systems can be opened at any time via the lever handle from the inside and with one turn of the key from the outside.

"Insured with the door just pulled shut!"

Automatic double latchbolt

The particularly robust, self-locking system GU SECURY Automatic 4 or Automatic6, e.g. for main and apartment entrance doors. Two Automatic latchbolts per locking point automatically throw 20 mm when the door is pulled shut and are secured against being forced back

Automatic double bolt

With the SECURY Automatic double bolt (ADR) locking type, the self-locking latchbolts are triggered first when the door is pulled shut and activate the hook bolts mechanically. At the same time, the hook bolts engage with the frame parts. The hook bolts move upwards to lock. This serves to protect against levering out during burglary attempts and ensures a high level of functional reliability. All locking elements are secured against being forced back.

Locking types – manual

Locking cam, roller

With the roller cams being adjustable, optimised gasket pressure and door tightness are achieved in the top and bottom areas of the door. The GU SECURY R is available with massive bolt/roller-cam, hook bolt/roller-cam and with 4 roller-cams.

Round bolt

The hardened steel round bolts with a projection of 20 mm and a bolt diameter of 11 mm fit precisely into the L&D striker and door frame. These are a secure solution when used with DIN steel door frames.

Massive bolt

The GU SECURY MR system provides you with a multi-point lock which is protected from being forced back – with two or four MR bolts depending on the requirements. Owing to the lock geometry, the same frame locking components used with the GU SECURY Automatic system can also be used here. The MR bolts are extremely resilient: a hardened steel insert means they cannot be sawn through.

Solidly locked!

Hook bolt

The GU SECURY SH system provides you with a multi-point locking system which is saw-through proof and hooks in behind the striker – it comes with either two or four hook bolts that move upwards when locked. This arrangement prevents the SH bolt from coming down on the striker if the door is lowered.

"Securely locked with hook bolts!"

Double bolt

The GU SECURY DR multi-point lock rolls the benefits of the SH bolt and MR bolt into one double bolt. Owing to the lock geometry, the frame locking elements of the GU SECURY Automatic 4 system (with Automatic double latchbolts) can also be used here.
