What is the Solex Double Cylinder D50SS 50MM used for?

The Solex Double Cylinder D50SS 50MM is a double‑ended door lock cylinder that provides secure keyed locking from both sides of a door. Unlike single‑cylinder locks (key outside, thumb‑turn inside), a double cylinder requires a key to lock and unlock from both the exterior and interior sides. This makes it especially suitable for external entrance doors where enhanced security is needed because it prevents easy unlocking through adjacent glass or openings.

The D50SS designation typically refers to a 50 mm double‑cylinder core with a stainless steel (SS) finish or housing, providing corrosion resistance and long‑term durability — ideal for varying climatic conditions such as the humid coastal regions of Kenya.

In a mortise or deadlock assembly, this cylinder replaces or integrates with the lock’s existing cylinder, allowing dual‑side keyed operation. It suits mortise deadlocks, multipoint locks, and other keyed locksets designed to accept modular cylinders. The double‑cylinder arrangement enhances security by eliminating unsecured internal thumb‑turns that can be exploited with simple tools.
