Performance & Safety
What makes this fixture valuable for buyers is its engineered wind load performance that maintains structural integrity across varying weather conditions. With EPA ratings ranging from 10.2 at 70 mph down to 3.6 at 120 mph, operators can select appropriate fixtures while maintaining safety margins for their specific geographic requirements.
From a safety perspective, the anchor base installation method provides secure mounting that distributes structural loads effectively into the foundation system. The 8 to 10-inch bolt circle configuration ensures proper load transfer while the 2.75-inch bolt projection allows for standard anchor bolt specifications.
In terms of longevity, the dual-layer protection system combining hot-dip galvanizing with powder coating creates a barrier against corrosion that extends operational life significantly beyond standard painted finishes. This reduces replacement frequency and helps maintain consistent facility appearance over time.
Setup & Mounting
The anchor base design streamlines installation by eliminating the need for concrete pouring around the pole base. Installation teams can prepare the foundation with standard anchor bolts positioned according to the specified bolt circle, then secure the pole directly to the prepared foundation. At 169 pounds, the pole requires standard lifting equipment but remains manageable for most commercial installation crews. The included 2 3/8 inch tenon provides immediate compatibility with standard commercial lighting fixtures, reducing installation time and additional hardware requirements.
Certifications & Warranty
- Manufactured to commercial lighting pole standards for structural performance
- Hot-dip galvanizing process meets corrosion protection specifications
- Powder coating finish applied according to industry durability standards
- One-year manufacturer warranty covers material defects and finish integrity
- Warranty support includes replacement coverage for manufacturing-related failures
