SDC’s 1590 series electromagnetic sliding door locks are compact locks with 850lbs of holding power packed into a small
steel mortise case. The lock is ideal for securing sliding or swinging, manual or automatic doors. Its durability for high frequency use and its mortise installation make it the choice of specification writers, owners and architects.
With only two parts, the lock mortised in the frame and the armature in the door, the lock secures the door in a closed position. When power is cut the lock releases instantly. When used with industrial sliding doors, two locks may be used to provide up to 1700lbs of holding power.
