Tier Rated Underground Enclosures (TRUE)
Tier 15 and 22 Advanced Composite Material Tapered Rectangular Handhole Enclosures
Broadband Equity Access & Deployment Program (BEAD) and Build America, Buy America Act (BABAA) compliant*
Charles Industries has achieved a major breakthrough in material science as applied to grade level enclosures. Utilizing a process first proven and perfected in the manufacture of wind turbine blades, marine vessels and aircraft, Charles has developed an Advanced Composite Material (ACM) formulation that, when molded, provides superior performance and structural integrity. TRUE exceeds industry tier loading standards while weighing up to 50-75% less than equivalent useable volume polymer concrete alternatives.
Charles’ Tier Rated Underground Enclosures™ (TRUE) are made from Advanced Composite Material using a Resin Transfer Molding (RTM) process. Combining the design flexibility of RTM and the strength of advanced composite materials, TRUE grade level enclosures provide Tier 15 and 22 performance with ease of handling and installation.
TRUE grade level enclosures have a tapered wall design that provides greater useable volume compared to competitive polymer concrete cover sizes. The grade level enclosure industry has long focused on product sizes based on cover or lid size. However, the majority of grade level enclosure usages are for bulk volume applications (i.e. cable storage, splicing, drop management, valve control and metering). TRUE grade level enclosures provide more useable volume than competitive models with the same cover size and depth.
The exterior surfaces of TRUE are finished with gelcoat, which cures to a durable, smooth finish resistant to ultraviolet degradation and hydrolysis. TRUE grade level enclosures are available in two standard colors, Graystone and Utility Green.
