Subterra Series Max Tier 22 Handhole (32x44x24)
Approved
BABA, BEAD
Compliant
Made in USA
Description
The Subterra Max Tier 22 handhole in the 32x44x24 internal size is the wide-footprint option in Norvant’s flagship heavy-duty line. It keeps the 24-inch working depth of the core size but opens up the plan area to 32 by 44 inches, giving crews more room for multiple duct entries, larger splice cases and cable racking on demanding roadway and high-load routes. The HDPE base and ArmorGalv steel-reinforced Impact Modified Resin lid deliver concrete-grade Tier 22 performance at around 108 lb, so the wider unit still installs without heavy lifting gear. The straight-wall, anti-heaving ribbed base locks into backfill to resist heave and settling after install. Like the rest of the Max Tier 22 range, this size accepts cable management, an optional locating puck and a custom logo plate or color, so hardware and branding stay consistent across a build. Engineered to exceed ANSI/SCTE 77 Tier 22, BABA and BEAD compliant and RUS pending, it is ready for federally funded programs and shares its spec and option set with the 24x36x24 and 32x44x45 variants.

Design Feature
Why This Matters
Norvant Solution
Standard Market Offerings
Lid Security in Flood Conditions
Heavy rain causes vaults to flood, pressure buildup lifts lids into traffic or they float away
Auto-Latch System – automatic locking prevents lid displacement under pressure
Manual friction-fit lids that can dislodge; requires separate locking mechanisms or weighted lids
Ground Movement Protection
Freeze-thaw cycles and soil heaving push vaults upward, breaking seals and damaging installations
Flared Anti-Heaving Base Design – wider footprint resists vertical displacement from frost and water action
Straight-wall designs rely on weight alone; vulnerable to seasonal ground movement
Structural Strength
Smooth walls requiring thicker material or composite reinforcement to achieve same load rating
Working Space for Splicing
High-density fiber deployments need room for splice cases, slack storage, and future cable additions
25% Larger Internal Capacity at same price tier – future-proofs against network growth
Standard internal dimensions force premature change-outs as take-rates increase
Asset Location & Management
Field crews waste time locating buried infrastructure; asset databases become outdated
Designed for Locating Puck Integration – optional sensor enables GPS mapping and digital asset management
No provisions for tracking technology; relies on paper maps or technician memory
