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.

• American ABYC H-27 – 500Lb static load test - TRUDESIGN Skin Fittings and Ball Valves meet the American ABYC H-27 – 500Lb static load test; Seacocks, Thru-Hull Fittings, and Drain Plugs – independently verified by IMANNA Laboratory Inc.
• For sizes 1¼” through to 3” the ABYC Collar it is not a requirement to meet this static load test.
• TruDesign ABYC Load Bearing Collar is required for the size ¾ and 1” to meet this static load test.
• The ½” does not meet the 500Lb static load test with or without the ABYC collar
• 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
