The Phoenix Sign Stand is designed with a pre-drilled square upright to accommodate multiple hole patterns found in most size signs. The Phoenix offers a simple and easy way to mount signs that are different sizes and shapes to a single sign stand with no fuss. You can raise and lower signs anywhere along the six-foot long upright for more flexibility. The recycled rubber base with steel plate firmly grips the road surface, while presenting a narrow profile. The Phoenix Sign Stand is NCHRP 350 certified, with a 120cm x 120cm, 0.80 aluminum sign.
