## Long description

Gerda Wkładka mosiężna bębenkowa 30-40mm 3 klucze is a brass cylinder lock insert designed for residential and light-commercial door security. The cylinder combines a compact 30–40 mm size with a cylindrical profile compatible with many standard euro-profile lock cases. Supplied with three keys, the insert provides basic keyed access control and replacement capability for worn or non-functioning cylinders.
Advantages
The brass construction ensures corrosion resistance and reliable mechanical performance under normal indoor conditions. A 30–40 mm length offers compatibility with a range of door thicknesses and frame configurations, while the inclusion of three keys allows immediate use and simple key distribution among household members or staff. The cylinder's straightforward design makes installation and future replacement quick for locksmiths or competent DIY users.
Suitable for (tasks / use cases)
Replacement of worn or damaged euro-profile cylinders in residential doors

Key specifications
Material: brass body for corrosion resistance
Cylinder type: euro-profile (cylindrical) insert
Length: 30–40 mm total cylinder length suitable for many standard doors
Operating method: mechanical key operation
Accessory: includes three keys
How to use
To install, remove the fixing screw from the door edge, retract the cam, and pull out the old cylinder. Insert the Gerda brass cylinder so that the cam aligns with the internal mechanism, secure it with the fixing screw and test locking and unlocking with the supplied keys. Ensure the cylinder length matches door thickness so the cylinder does not protrude excessively beyond the escutcheon or is recessed too far. If necessary, measure door thickness and adjust to a cylinder with an appropriate dimension.
Usage recommendations
Use the cylinder indoors or in sheltered external doors to avoid long-term exposure to direct weather. Periodically lubricate the keyway with a graphite-based lubricant recommended for locks and check mounting screws for tightness. For enhanced security, consider pairing this cylinder with compatible escutcheons and a reinforced door lock case.
