Ball End Fittings

Hayn Ball End Fittings are Type 316 stainless steel threaded ball fittings for Traditional Cable Rail systems, available in 1/4-28 and 5/16-24 right hand thread configurations to work in conjunction with Threaded Termination Studs, Threaded Termination Stud Turnbuckle Assemblies, and the Surface and Back Mounting Ball and Socket System. 

Strong Where It Matters

Ball End Fittings

The ball end fitting seats into a compatible socket to allow the cable to terminate at an angle without creating a bent or stressed wire end at the post — the same angle compensation principle as the Adjust-A-Ball, applied to the Traditional Cable Rail system. Both configurations share a 5/8" outside diameter and require a 1/2" diameter hole in the post for installation, keeping the mounting geometry consistent across 1/4-28 and 5/16-24 thread sizes. Select the thread size to match the corresponding Threaded Termination Stud or Turnbuckle Assembly being used on the same run.

Engineered In America Every Hayn fitting is designed and manufactured at our facility in Rocky Hill, Connecticut — the same American workmanship that has set the standard for stainless steel rigging hardware since 1950.
Cold-Worked Production Hayn fittings are cold-worked, not cast. That distinction matters: the cold-working process refines grain structure, increases fatigue resistance, and produces a fundamentally stronger component — one built to perform when the load comes on it.
Precision Manufacturing Our Rocky Hill production floor runs CNC vertical mills, CNC lathes, large-capacity mill-turn centers, and waterjet cutting systems — all configured to produce hardware that meets exact specifications, every time.
75+ Years of Excellence Hayn has been engineering and manufacturing marine and architectural rigging hardware since 1950. That track record isn't just history, it's the design knowledge, failure data, and continuous improvement that goes into every product we make.
