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.
