Cylinder Lock Core Grot G-700-0102 brass 30/40 mm with 70 mm length, 5 keys (1 pc)

Grot cylinder lock core G-700-0102 is a brass euro-profile door cylinder with asymmetric 30/40 mm dimensions and a total length of 70 mm. Supplied with five identical keys, this cylinder is intended for replacement or installation in compatible euro-profile fittings to provide mechanical access control for residential and commercial doors. The construction is suitable for standard key-operated locks where a single-sided or double-sided actuation with an asymmetric profile is required.

Advantages

The brass body offers corrosion resistance and stable mechanical performance under normal door usage. The asymmetric 30/40 mm sizing with a 70 mm overall length accommodates doors with unequal thickness on each side and allows straightforward replacement of existing euro-profile cylinders. Supplied with five keys, the product provides immediate operability and spare keys for multiple users or backup. The cylinder’s standard shape and dimensions make it compatible with a wide range of euro-profile lock cases and escutcheons.

Suitable for

• Replacement of worn or damaged euro-profile cylinders in residential doors
• Installation in commercial interior doors with euro-profile fittings
• Doors with asymmetric thickness requiring a 30/40 mm cylinder length
• Applications where five keyed copies are needed for household members or staff

Key specifications

• Body material: brass
• Profile type: euro-profile cylinder
• Dimensions: asymmetric 30/40 mm (70 mm total length)
• Operation: key-operated mechanical cylinder
• Number of keys supplied: five identical keys

How to use

Measure the door and existing cylinder to confirm the 30/40 mm asymmetric dimensions and 70 mm total length match the required replacement size. Remove the fixing screw from the lock case, withdraw the old cylinder, insert the new Grot cylinder so the cam aligns with the lock mechanism, and secure it with the fixing screw. Test the cylinder by operating the key from both sides to ensure smooth insertion, turning, and locking action before finishing assembly and refitting escutcheons or protective hardware.

Usage recommendations

For reliable operation, lubricate the cylinder periodically with a dry lubricant suitable for locks and avoid oil-based products that attract dust. Keep spare keys in secure locations and consider professional fitting if you encounter alignment issues or if the door has additional security fittings that require specific cylinder positioning.
