Modular Composite Enclosure — 24 × 36 × 24 in
FZ Tech modular composite handhole is engineered for outside plant (OSP) infrastructure: SMC grid-rib reinforced side panels with a Tier 22 load-rated cover, delivering an exceptional strength-to-weight ratio, corrosion resistance and non-conductive properties.
The flat-pack design ships four side panels and a load-rated cover, assembled on site with standard stainless steel fasteners.
- 280 sets per 40 ft HQ container — up to 60% freight savings vs. pre-assembled alternatives
- 1–2 installers, standard tools, no heavy equipment
- ANSI/SCTE 77 Tier 22 — 33,750 lbf (150 kN) proof load
- Non-conductive — no grounding required
Built for the install crew
Dual-material construction
SMC grid-rib side panels plus a load-rated cover — high stiffness, zero corrosion, non-conductive, outperforms HDPE.
Flat-pack modular design
