Cantilever Slide Gates
A cantilever gate rolls on carriages bolted to its support posts and hangs clear of the ground across the opening. With no track on the ground, there's nothing for gravel, mud, leaves or ice to jam. HomeGuide's chain link guide lists commercial cantilever gates from 6 to 30 feet wide at $1,200 to $3,000 or more before installation. Its black chain link guide puts vinyl-coated commercial rolling gates at $1,400 to $3,000 installed. A fully equipped commercial security gate runs $5,000 to $15,000 or more, according to HomeGuide's security gate guide.
Motorized slide gates have specific safety rules. DASMA's installer checklist calls for screening the gate so a 2¼-inch sphere can't pass through, up to the top of the gate or 72 inches, whichever is less. It also calls for covers on weight-bearing rollers 8 feet or lower, protected entrapment zones, and a separate pedestrian gate. Keypads, card readers and exit loops are covered on gate openers and access control.
