  • 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.

Made from up to 50% of post-industrial recycled material from COVID relief medical material production.
Learn more about the process:

  • COVID relief medical materials have been steadily mass-produced to aid in the ongoing fight against the pandemic. While proper material availability is incredibly important, the need for constant supply has lead to lots of unused waste.
  • Fortunately, Nuvo Iron was able to find an environmentally friendly use for this waste. We were able to manufacture and design a product that incorporates up to 50% of post-industrial recycled material from COVID relief medical material production.
  • In order to do this, we grind unused COVID relief medical material waste and create a mixture of up to 50% regrind, polypropylene, UV and colour additives and create the Nuvo Iron SPC23 Plastic Post Cap.

Sleek and classic, our new post cap beautifully accents any fence or deck project, a great choice for anyone looking to make an environmentally friendly addition to their outdoor space.
