Protection from theft
Anchor Barb Kits are intended to prevent the post from being pushed out of the ground during freeze/thaw cycles, as well as from attempts to pull them out by would-be vandals. Anchor barbs are available in fiberglass composite and in spring steel.
Carsonite customers may purchase Anchor Barbs in packs of 10 or have the Anchor Barbs installed at the factory prior to post shipment.
