This state of the art electro-magnetic locking device provides positive, instantaneous door control. Offered in models for single and pairs of out-swinging, in-swinging, sliding, and overhead doors. Filler plates, angle brackets, and other mounting adapters are available to satisfy a wide range of door and frame types and conditions. ULTRA-LOCK locking devices are inherently failsafe, releasing instantly upon command or loss of power. With no moving parts to wear, stick or bind; no mechanical linkages to bend or break; and no bolt travel time or misalignment to raise concern, both unlocking and locking are always accomplished with ease and efficiency. The rugged design and durable construction insures virtually endless actuations without fear of electrical fatigue or mechanical breakdown. This, combined with manufacturing to the most stringent quality control standards, allows Dortronics to offer a ten year limited warranty on all electromagnetic locks.
