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
