Square Flat Piling Caps
Square flat piling caps fit over square timber pilings, sealing the cut top against rain and standing water while keeping a flush, low-profile look along your dock line. If you are running square posts and want protection without a cone silhouette, this is the profile.
Ours are molded from UV-stabilized polypropylene and polyethylene, sized across the common square timber dimensions from 3.5 inches to 20 inches. Black gives the longest service life; white and gray are available where you want the caps to blend with railings and decking.
Need bird deterrence? Square cone caps handle that. Round pilings are covered under round flat caps. Browse all piling caps or call with your dimensions.
