Traffic Signal Cabinet Base Reference Guide 3. Determine Type of Cabinet

Hubbell traffic signal cabinet bases are constructed of strong polymer concrete and reinforced with a heavy weave fiberglass. Unlike concrete bases, polymer concrete bases are designed to break away when subjected to severe impact. This feature helps reduce the risk of serious injury or fatalities resulting from these incidents. Hubbell polymer concrete traffic signal cabinet bases also resist UV rays, chemicals and water absorption. Concrete bases are susceptible to damage caused by freeze/thaw cycles. Thermoplastic fiberglass bases can become brittle and eventually crack when exposed to the weather. The durability that Quazite provides means lower maintenance and life cycle costs.
