Since 1988, The Nantucket Post Cap Company has been creating fine post caps, finials, arbors, gates, benches, tables, and pergolas made out of the highest grade of redwood and cedar. All their high quality Arbors are made from the best grade of clear Western Red Cedar, so your fencing, deck, or other landscaping project is done right the first time.

Western Red Cedar has great resistance to moisture, decay and insect damage. This wood type also has exceptional dimensional stability. Your Arbor will stay straight, retain fasteners, and provide a firm base for many types of stains and paints, giving you a wooden pergola arbor that will hold up to the elements for years to come.

The Seaside Pergola Arbor is a simple yet elegant combination of straight lines and arches.  Taking the best of two beautiful garden structures, this pergola arbor is a really nice addition to any backyard, walkway, entranceway, or any other area of interest.

The single side posts provide a perfect place for your flowers or vines to climb, making this arbor one with your garden. This Garden Pergola Arbor is available in of sizes of 3-1/2' and 4' only. Add in some Low Voltage Lighting for a night time look that truly appleals to the senses.
