The Extension Tube is an add-on accessory for the Plamp Stake. It adds more than 10 inches to the height of the Stake. Multiple extensions may be used to achieve desired height. Keep in mind that as the height of the tube increases, rigidity decreases. The extension is UV protected to prevent yellowing and becoming brittle when exposed to the elements. The extension is also compatible with standard 3/4" Schedule 40 PVC pipe allowing you to get creative with hardware store PVC fittings and pipe to create custom setups in the field.
