Trellis is a very effective way of training climbers against a wall and can either be bought or made from scratch. Fixing it to the wall though can present problems but with a little care result can be both durable and effective.

Equipment:

  • Drill driver
  • Heavy duty SDS masonry drill and bit
  • Plastic wall plugs
  • Wood-screws
  • Spirit level
  • Claw hammer

Method:

  1. Choose a wood-screw about 50 mm thicker than the trellis, more if the wall is rendered, and some plastic wall plugs recommended for the size of the wood-screws.
  2. Fit the masonry drill with a bit the recommended size for the wall plugs, you may want to hire a drill in (a 4 Kg drill which takes SDS drill bits will be sufficiently large).
  3. Position the trellis where you plan to have it and drill through the trellis into the wall. Chose a place half way across the trellis and near the top. Always aim for the centre of a brick or stone, avoid mortar joints.
  4. Move the trellis and tap a wall plug into the drilled hole. Put the trellis back and thread a wood-screw through the hole you drilled in the trellis and into the wall plug. Tap the screw head to start it off and drive it almost home with the drill driver. Check the trellis is level and vertical, the first screw will support it, and tighten the screw until it is flush with the trellis surface.
  5. Drill a second hole through the trellis vertically below the first and near the bottom; checking the trellis is still level and vertical. Push a plug into the hole, there is no need to move the trellis, and use a wood-screw and hammer to drive the plug into the wall until you feel the screw bite into the plug. Tighten the screw with the drill driver.
  6. Carry on repeating the process in part 5 above so that the trellis is screwed to the wall every 600 to 900 mm, checking the trellis is firmly attached to the wall.
