Product Summary

Dài Two-Hole Pipe Straps (also known as Saddle Clamps) are manufactured according to DIN 1596 Và MSS SP-58 standards, widely used in plumbing, HVAC, electrical conduit, and industrial piping. Featuring

a contoured U-shape with two mounting ears, these Dài Two-Hole Pipe Straps provide a heavy-duty, rigid mounting solution for securing pipes, tubes, or cables directly to flat surfaces such as walls, ceilings, or

structural beams.

• ✔ High Load Bearing: The two-point fastening design distributes weight and vibration stress more evenly than one-hole clips, ensuring maximum stability.

•  

• ✔ Precision Fit: Engineered with a specific radius to match standard O.D. (Outside Diameter) of copper, PVC, and steel pipes to prevent rattling or movement.

•  

• ✔ Superior Corrosion Protection: Available in Hot-Dip Galvanized for construction and Marine Grade SS316 for chemical processing and offshore environments.

Key Features of Two-Hole Pipe Straps

• Rigid Reinforcement – Reinforced ribs on the strap body increase structural strength and prevent deformation under heavy pipe loads.

•  

• Easy Installation – Slotted or round holes on each wing allow for quick alignment and securing using bolts, screws, or anchors.

•  

• Smooth Edges – Precision-deburred edges protect plastic pipes and delicate cables from abrasion or cutting during thermal expansion.

•  

• Standard Compliance – Fully compliant with MSS SP-58 (Type 26) for industrial pipe hangers and supports.
