Short plate round with key hole for bit / skeleton key and swivel cover distancing 75mm Brass | GSV-No. 6643 A / 2

The short plate round with key hole for bit or skeleton key and swivel cover, GSV-No. 6643 A / 2, is a precision-engineered hardware component designed for mortise locks in interior doors. Constructed from high-quality brass, the plate combines excellent mechanical strength with long-term durability and natural corrosion resistance, ensuring reliable operation even under frequent use. Brass is particularly suited for hardware applications due to its robustness, wear resistance, and attractive finish, which remains visually appealing over time.

The round short plate features a precisely machined keyhole compatible with bit or skeleton keys, allowing smooth and accurate operation of the mortise lock. A swivel cover is integrated into the design to protect the keyhole from dust, dirt, and moisture, thereby enhancing the functional lifespan of the locking mechanism. In addition to functional protection, the swivel cover maintains a clean and refined aesthetic, concealing the keyhole when not in use.

The plate is designed for a center-to-center distancing of 75 mm, ensuring compatibility with a wide range of mortise locks. Installation is facilitated through the use of through bolts, which secure the plate firmly to door thicknesses ranging from 22–64 mm and 35–40 mm, providing torsion-resistant and stable mounting.

By combining a durable brass construction, protective swivel cover, and precise engineering, the short plate GSV-No. 6643 A / 2 offers a technically advanced, reliable, and visually appealing solution for mortise locks with bit or skeleton keys. It ensures long-lasting functionality, smooth operation, and elegant integration into interior door designs.
