This is our all new Heavy Duty MarJoint with a 9/16" through hole. MarJoints are fully rebuildable using a threaded collar instead of the weaker and cumbersome snap rings.

Additionally, we designed our MarJoints to be rebuildable through only one side of the joint.

As a result, you get a very strong joint that is fully supported (solid steel) on one end.

The MarJoint is built extremely tough! Features 30° of twist despite its robust design. Your search for a very strong and dependable joint ends here.
