Zurn QTALON and QISC Series clamps are widely used in hot and cold water plumbing applications for securing PEX tubing / pipings to floors, studs and joists. The QTALON Series tube talons comprise a J-hook clamp with a nail that eliminates the need for bonding agents, glues, and solvents. These nail clamps can be easily installed in both upward and downward directions to ensure a secure installation. The brand's QISC Series insulated pipe suspension clamps feature ribs to allow for tubing expansion and contraction and can easily fit 1/2 inch nominal tubing.
