How to build a CFA package:

Example: You need to bore 7 metres under a driveway for a 90mm conduit

  • 1) Choose the CFA Adapter to match your auger drive shaft
  • 2) Choose the diameter of the hole required. Note that it needs to be larger than the outside diameter of the bell end of the pipe.
  • 3) Choose how many augers you need to get 7 meters plus extra for clearance.
  • 4) Choose the diameter of the pilot.
  • 5) All but 1x CFA will require a joiner
  • 6) Every joiner will require 2x D-clips
  • 7) Plus, the Adapter and the Pilot will require 1x D-clip each.

So, your order could be:

1x 65mm Round to 1 3/4" Hex Adapter

5x CFA 115mm Hole Cut (7.5m OAL)

5x "HT" Hex Joiner 1 3/4"

1x Pilot 115mm Hole Cut

10x D-Clip 1 3/4"

Ps it is recommended to purchase at least 1x extra Joiner and D-Clip just in case you need them.
