Understanding ANSI/SCTE 77 tier ratings
Every below-grade enclosure Galloway stocks is rated to ANSI/SCTE 77, the industry standard that classifies boxes by the load they can support. The tier number indicates the maximum allowable static load in thousands of pounds on the cover and frame assembly. Tier 15 enclosures handle 15,000 lbs (pedestrian, lawn, and light vehicle areas), while Tier 22 enclosures handle 22,000 lbs (roadways and areas subject to occasional truck traffic). Specifying the correct tier for the installation location is critical—installing a Tier 15 box in a road crossing creates a safety hazard and a liability.
| Tier | Design Load | Test Load | Typical Installation |
|---|---|---|---|
| Tier 8 | 8,000 lbs | 12,000 lbs | Pedestrian-only areas, no vehicle access |
| Tier 15 | 15,000 lbs | 22,500 lbs | Lawns, sidewalks, light maintenance vehicles |
| Tier 22 | 22,000 lbs | 33,750 lbs | Roadways, driveways, parking lots |
