Emka's 1000 series quarter-turn insert locks have been around for years, but recently the company introduced a number of additional variants, following a technical development programme. The 1000 Series lock range offers IP65 and IP54 environmental protection levels and many different inserts, including triangle, square, double bit and key type. Key lockable options include barrel locks, wing handles, T&L handles as well as a key-captive version, which prevents the key being left in place. High security versions are also available to meet ASSA and KABA specifications.
