Able to withstand vandalism better than other crossbars, these mortise mount into a cutout in the door. Crossbars have a traditional design that is common in older installations. They open doors with a push and are often used on emergency exits. You can use them alone or mount an optional handle on the outside of the door. All can be cut to fit a range of door widths.

To determine door swing direction, stand on the side of the door where it swings away from you. If it opens to the right, select a right crossbar; if it opens to the left, select a left crossbar. Latch bolt projection is the length the latch bolt extends from the door's edge.

Protect your door from forced entry. These bars mount across doorways for extra security on top of standard door locks. Originally designed to secure office doors on construction sites, they’re powder-coated steel so they're strong and weather resistant. A cover keeps dust and debris from entering the lock, preventing it from freezing, corroding, and jamming. Fasten the mounts on each side of the door frame with the included hardware—only the bar is removed when unlocking them. They’re compatible with outward-swinging doors only.

Choose keyed alike locks if you need several locks that open with the same key. Choose keyed differently locks if you need locks that each open with a different key.

Bars with a combination lock allow you to set your own combination and change it at any time.

Add a bar extender to fit doors of a wider width. 36" wide bar extenders have seven adjustment holes and fit doors between 40" and 52" wide. 48" wide bar extenders have two adjustment holes and fit doors between 55 ½" and 57 ½" wide.
