Scope of use

How the connections work:

  • 90° Corners: No brackets are needed when panels are joined at 90°. The panel's edges match naturally to create strong corners.
  • Length Extensions (180°): To join two panels in a straight line for a longer length, use the Length Extender Bracket. This provides a seamless and secure 180° connection.
  • Outward 90° Corners (270°): To create an outward corner (effectively a 270° join), use the Corner Bracket for strength and stability.
  • Bracing : If you are worried about bulging in long extensions, use the bracing of suitable length.

Assembly is straightforward and designed for DIY installation.

  1. Bolt panels together using supplied fixings
  2. Leave bolts slightly loose during initial assembly
  3. Square up your planter
  4. Fully tighten all bolts with supplied spanners.
