Cylinder Lock Core Grot 30/35 mm (65 mm overall) Brass, 5 Keys, Single Piece

Grot cylinder lock core with asymmetric 30/35 mm dimensions (65 mm overall) is a brass euro-profile cylinder supplied as a single-piece insert with five keys. Designed as a direct replacement for compatible euro-profile lock cases, this cylinder provides the mechanical components required for standard door locking and access control in residential and commercial settings. The asymmetric 30/35 mm format means one side of the cylinder is shorter than the other, enabling fitment in doors with off-centre handle or lock positions.

Advantages

The brass construction offers corrosion resistance and durable mechanical strength for regular use. Supplied with five identical keys, the cylinder allows immediate installation and multiple-user access without the need for additional key cutting. The single-piece design simplifies replacement of worn or damaged cylinders and is compatible with standard euro-profile mortise lock cases used in many door systems.

Suitable for

• Residential entrance and interior doors using euro-profile cylinders
• Commercial office doors requiring a standard euro-cylinder replacement
• Doors with off-centre handle or lock positions that need an asymmetric 30/35 mm cylinder
• Renovation projects where existing euro-profile cylinders are worn or damaged

Key specifications

• Profile type: Euro cylinder (asymmetric)
• Dimensions: 30/35 mm (30 mm on one side, 35 mm on the other); overall length 65 mm
• Material: Brass body and core components
• Number of keys included: 5 identical keys
• Supply format: Single-piece cylinder insert

How to use

Install the cylinder into a compatible euro-profile lock case by removing the retaining screw from the door edge, sliding out the old cylinder, and inserting the new Grot cylinder until the cam aligns with the lock mechanism. Tighten the retaining screw to secure the cylinder. Test all five keys to ensure smooth operation and correct alignment before finalising installation. For best results, lubricate moving parts with a graphite or dry lubricant suitable for locks during installation and after any exposure to harsh conditions.

Usage recommendations

Use this cylinder in doors that match the asymmetric 30/35 mm dimensions; confirm the required side lengths before ordering. For enhanced durability, avoid exposure to excessive moisture and consider periodic lubrication and inspection. If higher security features are required (anti-snap, anti-bump, restricted keys), select a cylinder with those certified protections.
