Most products are build to pass a single tier. Ours are built to perform across every condition, every time.
ALLTIER™ TECHNOLOGY
Engineered to perform at every level
Many assume a Tier 22 enclosure is inherently stronger than Tier 15—but that’s not always true. Differences in test methods and load distribution mean some products can pass Tier 22 while failing Tier 15. That’s why APC leverages patented designs and proprietary material science to power our AllTier™ Technology—ensuring Maximus™ HD and Legacy Series™ exceed both standards independently for consistent, real-world performance across every tier.
NOT ALL TIER-RATED
PRODUCTS ARE EQUAL
Many assume a Tier 22 enclosure is inherently stronger than Tier 15—but that’s not always true. Differences in test methods and load distribution mean some products can pass Tier 22 while failing Tier 15.
Passing one tier doesn’t mean performing across all tiers, according to the standard
ONE TECHNOLOGY. EVERY TIER.
AllTier™ Technology ensures consistent structural performance across the full SCTE range — from pedestrian-rated Tier 5 to heavy-load Tier 22.
Instead of designing for a single test condition, we engineer for real-world variability:
- Changing Loads
- Different Installation Environments
- Real-World Use
Reliable performance—no matter the tier.
TESTED BEYOND THE STANDARD
AllTier™ Technology is validated through rigorous structural testing defined in SCTE 77 standards.
Our enclosures are evaluated under multiple real-world stress conditions, including:
- Cover Vertical Load Testing
- Lateral Sidewall Testing
- Vertical Sidewall Testing
- Lateral Lid Seat Testing
- Rigorous Installation Testing
- Cover Impact & Deflection
It’s not just about passing a test — it’s about performing through every condition those tests represent.
CONSISTENT PERFORMANCE
Engineered to meet every tier requirement — not just one.
REAL-WORLD RELIABILITY
Designed for changing loads, environments, and repeated use.
SIMPLIFIED SOLUTIONS
One solution across multiple applications — fewer compromises and streamlined inventory.
