This highly durable, yet lightweight sign post is constructed of a white powder coated aluminum post that prevents warping and remains straight even in harsh summer or winter conditions. It is easy to install in asphalt or concrete and utilizes our patented, anti-twist, reactive-spring assembly for optimal strength and performance. The compression spring is designed to allow the sign post to withstand low speed bumper hits and return to its original position without damaging the sign or vehicle. Our Sta-rite sign post is ideal for traffic parking lot locations. They are especially useful in lots without car stops. Anchors included. Made in the USA. **Our Sta-Rite posts are designed to support signs with maximum dimensions of 12” x 18” (Aluminum) and up to 18” x 24″ (HDPE)**
