Detailed Engineering Specifications

Engineered for reliability and performance, this 3" polycarbonate U-bolt features an inside width (A) of 4.30" and an inside length (B) of 5.98". The bolt threads are standard 1/2"-13 UNC. Constructed from high-strength polycarbonate, it offers exceptional resistance to a wide range of chemicals, UV radiation, and extreme temperatures (-40°F to 250°F). Its non-metallic composition ensures electrical insulation, preventing galvanic corrosion and short circuits. This makes it an excellent choice for marine, chemical processing, water treatment, and outdoor infrastructure applications requiring durable, low-maintenance pipe support.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening U-bolt nutsTighten nuts until snug, then an additional 1/4 to 1/2 turn. Avoid excessive force that could deform or crack the polycarbonate.
Using incorrect thread size for nuts/washersAlways verify the 1/2"-13 thread size of the U-bolt and ensure compatible fasteners are used.

Common Applications

  • Marine piping systems
  • Chemical processing plants
  • Water and wastewater treatment facilities
  • Outdoor conduit and pipe support
  • Electrical grounding systems

⚠️ Engineering Warnings

  • Ensure the maximum operating temperature of 250°F is not exceeded.
  • Do not use in applications requiring high tensile strength or load-bearing capacities exceeding the material's limits.
