3-inch x 3-inch Westbury aluminum flanged post kits for residential come with base plate cover and cap included. Westbury 3"x3" post kits have a .095" thickness of post wall, and are a great look when paired with Westbury top rails. 3" posts are between 2" and 4" posts, and offer a larger post look without being too bulky. Like other Westbury posts, the leveling plate is included, and all exposed parts are powder coated. Westbury is made by Digger Specialties.

Black three-inch posts are in stock, bronze, and white must be ordered specially.

Westbury Post 3 in. x 3in. Posts are a great addition to Westbury railing lines, and are compatible with all Westbury aluminum railing collections including Tuscany C10, vertical cable, C80 VertiCable, three-rail C30 Riviera, glass infill C70 Veranda, and more!

3" Posts are available in Black with other profile colors available by Special-Order
