A heavy, large frame enclosing the gate side frames / gate uprights (required on all gates), this additional support bracing is automatically fabricated into all single swing gates wider than 6 feet and double swing / driveway / estate gates wider than 12 feet. This heavy duty frame runs along 3 sides of a leaf (like a “U”) and vitiates the need for the antiquated diagonal brace used by so many other brands. Residential Gates: 2″ x 2″ FRAME. Commercial Gates: 2″ x 2″ FRAME. Industrial Gates: 2.5″ x 2.5″ FRAME.
