Short plates round with key hole and swivel cover distancing 75mm in Brass for mortise locks with skeleton key | GSV-No. 6643 A

The short plates round with key hole and swivel cover, GSV-No. 6643 A, are precision-manufactured hardware components designed for use with mortise locks operated by skeleton keys. Constructed from high-quality brass, the plates combine mechanical durability with a decorative and traditional appearance, making them suitable for both classic and modern interior door applications. Brass as a base material provides excellent wear resistance, stability under frequent use, and long-term corrosion protection, ensuring reliable function over many years.

The design incorporates a round short plate with a precisely machined keyhole, specifically adapted for bit or skeleton keys. An integrated swivel cover is mounted over the keyhole, providing effective protection against dust, dirt, and accidental ingress of foreign particles. This feature enhances the longevity of the lock mechanism by reducing contamination and wear, while also contributing to a clean and uniform appearance on the door surface.

The plates are designed for a standard center-to-center distancing of 75 mm, making them compatible with a wide range of mortise locks. Installation is facilitated by the inclusion of through bolts, which ensure a secure and torsion-resistant fixing across the entire door leaf. These bolts are suitable for door thicknesses of 22–64 mm as well as 35–40 mm, providing versatility for different door constructions.

With their combination of functional engineering, protective swivel cover, and robust brass construction, the short plates GSV-No. 6643 A offer a reliable and aesthetically pleasing solution for interior door applications. They are particularly well suited for maintaining the authentic character of doors fitted with skeleton key mortise locks, while ensuring dependable daily use.
