The Spreest S4A-405D code handle is a robust and easy-to-use security solution that does not require power or batteries.
Thanks to the purely mechanical combination system, you can open the door with your own, individually set code – without a key, without an app, and without the risk of draining the battery.
The handle is waterproof , making it perfect for use outdoors.
The S4A-405D mechanical lock is equipped with an integrated body with a handle and space for a lower lock (bolt) , which increases security and allows it to be used in doors requiring additional locking.
Perfect for gates, wickets, gazebos, sheds, garages, basements, utility rooms, server rooms, tool cabinets, boiler rooms and garbage bins – wherever durability, resistance to external conditions and independence from electronics are important.
Once the door is closed , the lock automatically locks, ensuring security without the need for additional locking.
