Overview
The Four-Fold GT™ from Door Engineering is a trackless folding gate system designed for high-speed perimeter security access at commercial and industrial facilities. Unlike conventional sliding cantilevered gates that require a ground track and significant lateral clearance, the Four-Fold GT folds its four panels into a compact stack using free-standing columns with column-mounted operators. The result is faster access, less space consumed, and fewer moving parts to maintain.
Features & Benefits
Speed is one of the primary advantages of this gate system. Openings up to 16 feet wide can be fully opened in under seven seconds, making it significantly faster than a conventional sliding cantilevered gate. Standard configurations accommodate openings up to 20 feet wide with unlimited headroom clearance, so the gate fits locations where overhead obstructions or low structures rule out other barrier types.
Because there is no ground track, the gate eliminates one of the most common failure points in traditional sliding gate systems. Ground tracks collect debris, ice, and sediment that cause jams and require regular cleaning. The trackless design avoids these issues entirely, reducing maintenance and improving reliability in harsh outdoor conditions.
The Four-Fold GT is UL325 Listed, confirming it meets safety standards for automated gate operation. A convenient manual release is included for operation during power outages, with an optional high security locking access cover available for facilities that require controlled manual override access. Minimal moving parts contribute to high cycle durability and lower long-term maintenance costs compared to swing or slide gate alternatives.
Applications
This gate system is designed for perimeter security at facilities where controlled vehicle access, fast throughput, and durability are essential. Common applications include manufacturing plants, distribution centers, government and military installations, utility substations, data centers, corporate campuses, parking structures, and any commercial property where a perimeter barrier must open and close frequently without sacrificing security or speed.
The compact folding design also makes the Four-Fold GT well suited for sites with limited lateral space. Where a conventional sliding gate would need a full gate-width of clear run alongside the fence line, the folding panels stack in place — a significant advantage on constrained lots or sites with adjacent structures.
Specifications
Standard opening sizes accommodate widths up to 20 feet. Gates up to 16 feet wide open in under 7 seconds. The system uses free-standing columns with column-mounted operators and requires no ground track installation. The Four-Fold GT is UL325 Listed and includes manual release for emergency or power-loss operation.
