Supply List:

  • Correctly sized window box
  • Mounting bolts
  • Stud finder
  • Pencil or marker

How To Install:

  • Find the wooden studs beneath vinyl siding. You will be drilling straight through in order to anchor mounting bolts right into studs.
  • Measure your garden container to determine the distance between mounting brackets or holes in the frame. You will align this with your stud spacing.

Note: If using a Hooks And Lattice Window Box made of wood, composite PVC or one of our metal cages, your container is compatible with standard 16″-18″ stud spacing.

  • Use window box measurements to identify mounting position. Then mark your spots on the vinyl clearly to guide drilling.
  • Drill starter holes into siding. Just enough to give the bolt an opening that will help to guide it through.
  • Thread your first bolt through a pre-drilled mounting hole on the window box. Depending on their position, either begin with one side or, if there’s a center bracket or mounting tab, begin here.
  • Attach your container to siding. Depending on how comfortable you are holding up the weight of your window box, this part can be a one or two-person job. While supporting the full weight of the planter, drill in your first threaded bolt all the way through to wood siding, just shy of tightening all the way.
  • Finally, add remaining bolts and repeat the step above. Once the last is in and you’ve checked to make sure the display is straight, tighten bolts the rest of the way to secure the mount.

Now you’re ready to try out all of your favorite container garden arrangements for spring, summer, fall and winter. For homes in colder climates, be sure to choose a weather resistant flower planter or choose window boxes with removable liners that are easy to winterize and store.
