When you uncoil a roll of PEX Tubing, it will have a tendency to keep it's roll shape and want to coil back if given the chance. This is problematic when you are trying to lay out loops for radiant heat or a radiant heat installation. To make sure that your tubing goes, and stays, exactly where you want it, you can use a tube talon to secure it down to wood. These tube talons include a nail to secure the PEX pipe into the wood.
