Modular Composite Enclosure — 30 × 48 × 24 in
The larger sibling of our 24×36×24 chamber, built for the same one-shot SMC molding process and Tier 22 load rating, with more internal room for splices, splitters and slack storage at busy distribution nodes.
- Tier 22 load-rated cover — 33,750 lbf (150 kN) proof load
- ~200 sets per 40 ft HQ container
- SMC side panels — corrosion-free, non-conductive, no grounding
- Flat-pack field assembly with standard stainless steel fasteners
Built bigger, built the same
One-shot SMC molding
Grid-rib reinforced composite side panels give a high strength-to-weight ratio with no welded seams and no corrosion path.
Flat-pack shipping
Four panels plus a load-rated cover per set — roughly 200 sets load into one 40 ft container, cutting freight versus pre-assembled alternatives.
Fast field build
1–2 installers, standard tools, minutes to assemble. No crane, no heavy equipment.
Tier 22 rated
33,750 lbf (150 kN) proof load cover, suitable for parking lots and roadways per ANSI/SCTE 77.
Safe by material
Non-conductive composite means no grounding requirement and no stray-current corrosion.
In-house options
Molded logo, custom pigment, cable-port knockouts and internal brackets produced on our own tooling.
