Folding security gates are made with strong 3/4" 14 gauge channel steel. These rolling security gates have an exclusive non-interference design that preserves the integrity of durable gray powder coat finish for a longer life. Zinc-plated rivets help prevent corrosion. Barricade security gates come complete with smooth rolling wheels and a padlock lug (lock sold separately). Safety Gates fold complete and swing up to 180 degrees for an unobstructed clear opening. Gates can be either recess or surface mounted and allow easy installation (hardware not included).
