The racks accommodate different size poles and are adjustable for optimal sun angle from 15° to 65° in 10-degree increments. They can be rotated on the pole for manual tracking. Stainless steel module mounting hardware is included. Anchor bolts and poles are not included. Standard racks have mill-finish aluminum module rails with painted steel pole collar and strong back. Mounts are available in galvanized steel and anodized aluminum.
