The Berkshire Curbside Mailbox presents an impressive face. The one piece cast aluminum door features deeply cut details with a rich, leather grain textured panel. The stainless steel spring hinge and magnetic catch will keep the door secure and the rust proof cast aluminum body construction creates a weather resistant mailbox. Also includes up to five 2 inch tall brass self adhesive address numbers. The Springfield Series Mailbox Post features a 4″ x 4″ x 78″ smooth square post. Made entirely of aluminum with stainless steel components to eliminate rusting. Direct burial installation is required.
