The welcome return of the CHUBB 3C20 is here!  This much sought-after lock has been a favourite for years, taking the principle design of the Chubb Detainer locks and redesigned to accept a euro cylinder, these allow for a high degree of versatility with regards to making use of keyed-alike and master-key cylinder suites.

These beautiful Chubb locks were rebranded as the UNION C-Series but still represent the same quality and functionality that we know and love.  This is backed by UNION's bold 15 year guarantee!  This in itsself speaks volumes about the quality of these locks, as does the reputation that they still hold to this day.

So if you're looking to upgrade chubb detainer locks to euro profile locks then this is without question, the simplest and most effective way to make the switch!

With approval for use on 60 minute fire doors (and 30 minute fire doors) under the grading of EN-1634-1, you can also use this in your commercial premises where fire doors are used.

With high resistance against brute force attacks and sawing attacks, as well as independently operated internal levers which are specifically designed to frustrate any manipulation attempts on the internal mechanisms, it is most certainly worthy of playing host to high security euro cylinders.

With holes in the lock case designed specifically to accept bolt-through furniture fixings (B17), these locks would work well with high security cylinder escutcheons. Don't forget about the door handles either! To view our full range of door handles, please click the link: Door Furniture
