Codelocks has announced the CL6000, a new heavy duty electronic push-button lock with a cylindrical latch that has been tested for fire safety and durability to the American National Standards Institute (ANSI) grade 1 - the highest level of accreditation.

The ANSI has a grading system that measures the security and durability of locks. Different types of door locks are tested under different ANSI standards and the grade 1 accreditation proves a product's robustness against heavy use.

The CL6000 product has been accredited to the ANSI/BMHA standard A156.2-2003 and A156.25-2007, for door hardware covering locks and handle sets. It also has a UL/ULC fire rating of three hours. "This product was originally developed for the North American market, where specified products for many commercial applications require grade 1 certification," says Grant Macdonald, managing director of Codelocks.

"In the UK we have heavy duty locks designed specifically for high traffic areas - in hospitals or schools for example - but now we can offer a product to customers that has achieved the highest level of accreditation for its durability together with a three hour fire rating." Each CL6000 lock has full size lever handles and is designed for use as a primary lock on internal and external doors.

The CL6000 locks are available in brushed steel at a list price of £285 and are available to order immediately from http://www.codelocks.co.uk/Product-Family/CL6000.aspx or by calling free phone 0800 393405.
