Product Summary
The Fortress Box Frame Cantilever Slide Gate is a cantilever system designed to handle the forces of gravity and wind using box frame construction and stainless steel cable. Diagonal cross members eliminate lateral sway. Contact us today to discuss this barrier in more detail. We also invite you to request drawings and specifications and take advantage of our extensive in-house resources.
Features & Benefits
- Fabricated from aluminum alloy extrusions for light weight and durability; the standard design closes single clear openings up to 60 feet wide.
- Multi-panel sliding gate designs available for heights above 8 feet.
- Primary members (top and bottom) are “P” shaped custom extrusions in cross section.
- Vertical members alternate between 2 inch x 2 inch and 1 inch x 2 inch in cross section and spaced at a distance not to exceed the gate height.
- Outside frame-to-frame width measures 24 inches.
- Separate semi-enclosed double tracks of extruded aluminum alloy welded to the top primary member.
- Gate is supported by four posts and two tracks containing self-aligning, 4 or 8-wheeled (depending on size), sealed lubricant ball-bearing truck assemblies.

Frequently Asked Questions
TYMETAL has been in the perimeter security solutions market since 1985. With more than three decades of experience designing, manufacturing, and installing the Fortress Box Frame Cantilever Slide Gate, we have encountered many questions along the way. Explore a few of the common questions we are asked below. If you don’t find the answers you’re looking for, feel free to contact us by phone at 888-978-4283 or online.
Are box frame gates compatible with crash-rated or anti-ram reinforcements?
TYMETAL Fortress Box Frame Cantilever gates can be configured with crash-rated reinforcements for anti-ram applications. The box frame construction provides a structural foundation that can be upgraded to meet ASTM F2656 crash test standards when combined with the appropriate foundation anchor system and support post design specified by TYMETAL engineering.
What automation options and safety interlocks are available?
The Fortress Box Frame gate is compatible with electromechanical and hydraulic operator systems and supports the full range of UL 325-required safety devices including photo eyes, loop detectors, and obstruction-reversing sensors. Control interfaces accommodate card readers, keypads, and remote operation systems for integration into existing access control infrastructure.
What routine maintenance tasks keep the box frame system performing at peak efficiency?
Routine maintenance for the Fortress Box Frame includes lubrication of roller bearings and hinge points, inspection of the box frame for dents, weld cracks, or corrosion, and verification of roller alignment and contact with the support rail. The structural frame’s closed box profile limits moisture intrusion into the frame interior, but drain holes should be kept clear to prevent water accumulation.
