The Klo-Shure 9-Series Insulation Clamp is sized for use with fiberglass insulation. Due to its unique design, the Klo-Shure Insulation Coupling fills the void left by your typical strut clamp, allowing the contractor to secure tube and pipe runs against damage from shock and vibration, while fully insulating the tube and pipe runs. The Klo-Shure 9-Series ensures a complete vapor barrier, eliminating mold and corrosion risk, making it ideal for use in the plumbing and HVAC industries. It supports OD tube sizes between ⅝” - 3 - ⅛”, nominal iron pipe sizes between ½” - 3”, insulation wall thickness between 1/2" - 2", and is acceptable for horizontal, vertical, and inverted installations.
