Plastix Plus has designed a line of tool mounts for most newer model rescue tools. These mounts are made of high grade HDPE plastic and are constructed using a thermoplastic welding process for long lasting strength and durability. The plastic is very forgiving on the tool and will not scratch or mar like steel or aluminum. You spent a lot of money on your new tools. Why destroy them by piling them up in a compartment and letting them ride loosely?
