The SDC 1565 Hi/Shear EMLock from Security Door Controls features a 1.3-ton holding force. Ideal for commercial and industrial access control applications, the Hi/Shear is compatible with any access control system. It incorporates a proprietary field-adjustable, door static sensor that energizes the lock only when the door is fully closed and at rest, eliminating the noise and alignment problems associated with shear locks that require mechanical interaction to cause the door to lock.
