Which describes ASTM Type II, Class 2 Cantilever Gate?

• A. Two posts with internal rollers inside a C-channel; fixed rollers; bottom panel has guide rollers
• B. Four external rollers with no internal guidance
• C. A cantilever gate with no posts and a floating frame
• D. A vertical pivot system with wind shields

Answer: (A)

The key idea here is how a Type II, Class 2 cantilever gate is built to stay strong and move smoothly. In this design, two posts anchor the gate system and support the cantilever arm. The gate itself is guided by rollers that sit inside a C-channel, giving controlled, enclosed guidance rather than loose, exposed hardware. Fixed rollers bear the weight and keep the gate stable as it slides, while bottom rollers on the panel provide additional guidance to maintain proper alignment and prevent sag or misalignment along the ground track. This combination—two supporting posts, internal rollers inside a channel, and bottom panel guidance—delivers a robust, stable cantilever operation suitable for higher wind loads and frequent use, which is why it best describes ASTM Type II, Class 2. The other descriptions describe different configurations (such as no internal guidance, no posts, or a pivot-style system) and don’t match this specific cantilever setup.
