The SDC GL160 and 260 series electromechanical GateLoks are designed to provide access control and remote locking and unlocking capability for manual or automatic chain link, tubular steel and wrought iron sliding or swinging gates. Available in either failsafe (locked when energized) or failsecure (unlocked when energized) the electromechanical GateLok provides a higher degree of security than electromagnetic locks. Locking and unlocking may be accomplished with an access control such as a card reader, digital keypad or remote control. All GateLoks are designed for a 3" (76mm) fence post and 2" (51mm) gate post and are adaptable to smaller sizes.
