A spring-loaded socket locks your gas spring to the ball stud—squeeze the ends together to attach and to release. Thread these ball socket end fittings onto gas springs. They require a ball stud or ball stud mounting bracket (sold separately) to mount gas springs.

Select end fittings with a thread size that matches the rod and end thread sizes of your gas spring. The fittings will increase your gas spring's extended and compressed lengths, so add the Length 1 value for each fitting you attach.
