UNION has revised and redeveloped the standard finish of its keyULTRA master key system to ensure it complements the rest of its architectural hardware selection.

The patented cylinder range utilises DuraPIN technology to protect the key and cylinder assembly and to prevent unauthorised copies being made.

Available in six finishes, including; brush satin nickel, polished chrome, satin chrome, polish brass, satin brass or antique brass, the keyULTRA range features a 48 hour cylinder production lead time.

The product has been developed to meet the requirements of BS EN 1303:2005 and is resistant to picking, bumping, drilling, and plug extraction. The master key system is also proved for use on 60-minute fire doors in accordance to BS EN 1634-1:2000 – fire resistance tests for door and shutter assemblies.
