Folding Security Double Gates

Mount gates on each side of the doorway and lock them together in the center to secure doorways and other large openings without sacrificing visibility and air circulation. When not in use, each side of the gate collapses and swings out 180° to keep doorways unobstructed. Each side rolls on a caster for smooth opening and closing.

Gates mount inside or outside your door frame. Add a padlock (not included) to lock the gate.

16 Gauge—16 gauge gates are lighter in weight than 14 gauge gates. Install them as a security barrier in receiving doors, retail aisles, or school hallways.

14 Gauge—14 gauge gates are stronger than 16 gauge gates for a more secure barrier. They’re often installed in commercial buildings or entryways with high foot traffic.

Galvanized Steel—Made of galvanized steel, these gates are strong and can stand up to rain when installed outdoors.

Three Locking Bolts and Five Locking Bolts—Gates with three or five locking bolts can be locked at multiple points across their width for added security and support.

Folding Security Gates

Mount gates on one side and lock them on the other to secure doorways and other large openings without sacrificing visibility and air circulation. Secure them on the inside or outside of door frames, or between posts, bollards, pallet racks, and walls. When not in use, these gates collapse and swing out 180° to keep doorways unobstructed. They roll on a caster for smooth opening and closing. Gates mount on the left side and lock on the right side. The right side is determined by facing the gate from the outside.

Add a padlock (not included) to lock the gate. Gates 7 ft. and wider include a locking bolt in the center of the gate for added support and security.

16 Gauge—16 gauge gates are lighter in weight than 14 gauge gates. Install them as a security barrier in receiving doors, retail aisles, or school hallways.

14 Gauge—14 gauge gates are stronger than 16 gauge gates for a more secure barrier. They’re often installed in commercial buildings or entryways with high foot traffic.

Galvanized Steel—They’re made of galvanized steel so they’re strong and can stand up to rain when installed outdoors.

Mobile Folding Security Gates

Roll these portable gates wherever you need temporary access control. Use them to block off machinery and hazardous areas of your facility or hook multiple gates together to create a secure enclosure. When you're finished, fold them up and roll them into storage.

Each gate includes a bar for mounting these gates to a wall. Lock them in place with a padlock (not included).

16 Gauge—16 gauge gates are lighter in weight than 14 gauge gates. Install them as a security barrier in receiving doors, retail aisles, or school hallways.

14 Gauge—14 gauge gates are stronger than 16 gauge gates for a more secure barrier. They’re often installed in commercial buildings or entryways with high foot traffic.

Galvanized Steel—They’re made of galvanized steel, so they’re strong and can stand up to rain when used outdoors.

Door Locking Bars

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.

Unlocks with Combination

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