For use alone or as part of an access-control system, these locks use electromagnetic force to hold double doors closed. Control the locks with a push-button switch or keypad door control (sold separately). When power is interrupted, they instantly release. The locks must be hardwired.

Locks include two strike plates to control two doors at once. They mount under the door frame header and lock the instant doors are closed. A 5/8" thick filler plate (sold separately) is required if the mounting surface on the frame is less than 2" wide.

Optional battery backup packs supply power during power interruptions.

These latches arrive ready for single-point latching; for more holding power, add a latch kit for two-point latching or two latch kits for three-point latching (latch kits sold separately).

Style A latches allow selecting the turn direction when mounting the cam. They come with a reversible offset cam to provide variable latching-distance ranges depending on the cam position.

Style B latches allow selecting the turn direction when mounting the cam.

Style C latches have a handle that lifts and then folds out of the way when not in use.

Multiple-point latch kits have a rod and a rod guide.

Choose this keyed alike lock if you need several that open with the same key. Side, top, and bottom latching points secure large, heavy doors that are subject to strenuous use, such as those on trucks and large access doors. The lock has two handles; an outside handle with a spindle that mounts through the door and an inside safety-release handle that opens the latch even if the outside handle is locked. It has a straight cam for side latching. For top and bottom latching, rods connect the top and bottom slide bolts. Use a hacksaw to cut rods and spindle to size. Select the turn direction of the lock when mounting the cam.

Operate latches around corners and other obstructions—a flexible cable connects the latch to the handle, lever, or push button. Maximum cumulative bend is the combination of individual bend angles the cable can withstand.

Zinc-plated steel latches are mildly corrosion resistant.

Black zinc-plated brass latches have good corrosion resistance, so they’re often used in marine environments.
