This real estate sign is made from 1/8" (9 gauge) steel. The metal stakes are ideally designed for use with signage made from corrugated materials, namely plastic, which is ideal for outdoor usage. Each real estate sign is designed such that the stakes slide directly into the fluted material. The use of 4-mil corrugated board is recommended. Due to its size, the real estate sign works best with 24" x 18" signs or smaller. With this real estate stake, you signage can be displayed on one side or both sides to maximize the graphic exposure. A for-rent stake, real estate sign can be inserted directly into the ground with no hardware required. Please Note: We do not include a sign with the unit. Customers will have to provide their own signage.
