Harbor Crest 3" Outside Corner Harbor Stone

The Harbor Crest 3" Outside Corner in Harbor Stone is a vinyl siding trim accessory designed to create a clean, finished edge anywhere two exterior walls meet. It forms a durable �corner post� that the siding panels lock into, helping the installation look crisp while protecting vulnerable outside corners from wind, moisture, and everyday impact. Harbor Stone is part of the Harbor Crest color palette, making it easy to coordinate this corner trim with matching lap siding for a seamless, unified exterior.

Harbor Stone outside corner uses and installation fit

Use a 3" outside corner when you want a balanced corner detail that pairs well with standard Harbor Crest lap profiles (Double 4, Dutchlap 4.5, Dutchlap 5). The corner post helps maintain straight vertical lines, provides a consistent pocket for panel expansion/contraction, and delivers a professional finish around corners, bump-outs, and garage returns.

Design Ideas and Color Pairings

For a timeless exterior, pair Harbor Stone siding with white trim and black shutters. For a softer, modern feel, combine it with warm off-white trim and a natural wood or dark bronze front door.
