This construction key set features a square key and a master key, both engineered for reliability in door hardware, lock cylinder installation, and maintenance tasks. The keys incorporate a built-in cylinder length measuring scale-etched directly onto the key body-for quick reference during fitting. Constructed from zinc alloy, they offer balanced strength, dimensional stability, and resistance to everyday wear. Their slim, ergonomic profile ensures comfortable handling and convenient storage. Ideal for professionals and home users working with standard euro-profile or similar cylinder locks.
