Load Bearing Collars

Compliant to North American ABYC H-27 Standards

Load Bearing Collars

TruDesign Load Bearing Collars are designed for use with TruDesign Skin Fittings and Ball Valves.
With the Collar in place, the Skin Fitting-Ball Valve-Hose Tail assembly will withstand a 500 lb (227 kg) static force applied to the Hose Tail end of the assembly, for a minimum of 30 seconds – complying with North American ABYC H-27 standards.

Note: TruDesign 1 1/4", 1 1/2" 2" Skin Fittings meet the requirements of H-27 500Lb standard (i.e. without a Large Collar installed). Adding a Large Collar to assemblies of this size increases the overall strength and protects the vulnerable exposed section of thread on the Skin Fitting.



  • ABYC H-27 500Lb compliance for 1”, 1¼”, 1½”, and 2" sized assemblies. Independently verified by IMANNA Laboratory, Inc. (USA).
  • Compact footprint
  • No additional bolts or fasteners through or on to the hull
  • Ability to retrofit to existing TruDesign assemblies
  • Compatible with all hull types across a wide range of hull thicknesses – download product info sheet above
  • Shrouded protection
  • Fool-proof assembly - if not snug when tightened the Skin Fitting's length will need shortening. See info sheet.
  • Manufactured from a glass reinforced nylon composite
  • Immune to corrosion and electrolysis
