Made of UV rated plastic for long outdoor life, Arlington entrance caps come with adapters that fit a range of Sizes, so you will have fewer products to stock. Our new PVC1020 handles 1/2, 3/4 and 1 in PVC, rigid and EMT one product for all three Sizes. Used for 1/2 in, PVC1020 costs less than a comparably sized aluminum cap. The savings is even greater on the 3/4 and 1 in Sizes.
