    Example: a nominal or dressed 4″ x 4″ post cap fits a post that measures 3.5″ x 3.5″
  • When a post cap fits a rough lumber or undressed post, the post size is the same as the measurement listed.

  • How to Install a Post Cap
    • Once all panels are installed at the preferred height, simply cut the posts at an elevation that best suits the cap style.
    • This may be achieved with a hacksaw, reciprocal saw or band saw.
    • Make certain that all sharp metal shavings have been removed from the panel.
    • Please note that exact post heights may be set prior to installation to avoid any cutting.
    • Once the posts have been set to height, pop out the screws included on the inside of the cap.
    • Simply install the cap over top with a rubber mallet to create a snug fit and screw the screws into the sides of the cap for a long-lasting fit.

What Our Past Clients Have To Say

  • High Quality and Locally Made

    "I have been working with the Tru North and Clubhouse products for awhile now and having 2 excellent decking products made here in Ontario is great....They really stand behind their products and my clients have been thrilled with their decks."

  • Easy To Install

    "Between their clubhouse and trunorth product lines, trunorth decking offers beautiful, long lasting products that, speaking as an installer, are very easy to work with. I'd recommend these products to anyone!"

  • Handles Our Harsh Climate

    "They are a Canadian manufacturer based in Brantford - another major factor in our decision....After a summer of intense sun and heat, a typical bone chilling Muskoka winter, and a quick spring power wash, the deck looks as good as when we first installed it."

  • Durable and Kid Friendly

    "Very Happy with our TruNorth Deck. Great looks and low maintenance is why we chose this product that doesn't use any saw dust. Plus my kids don't get slivers like they do on wooden decks."

Clean & Care Info

Basic Cleaning Recommendations

Although TND products are low maintenance, TND recommends periodic cleaning to help maintain the natural wood grain of the product. For best results power wash using dish soap detergent. The recommended maximum pressure is 1700 psi for TND decks. A fan tip nozzle must be used along with the proper cleaning product. Spray in the direction of the brush/grain pattern to avoid damaging the product. Use caution not to damage the material and always take the proper safety precautions when operating a power washer.
