The Subterra Max Tier 15 handhole in the 24x36x24 internal size is the mid-tier workhorse for mixed-load sites that need more than pedestrian performance without the cost of Tier 22. The same HDPE base and Impact Modified Resin lid keep it light at around 108 lb and quick to install. A smooth sidewall locks it into backfill and stops settling, with cable management, locating puck and branding options. -
The Subterra Max Tier 22 handhole in the 24x36x24 internal size is Norvant's flagship enclosure for roadway and high-load sites. An HDPE base and Impact Modified Resin lid deliver concrete-grade load performance at around 108 lb, so a small crew installs faster and more safely. This mid-footprint size handles everyday splice and slack work, with room for cable management, a locating puck and custom branding.
