A gas strut needs an articulating end that lets the panel swing as it opens; a ball joint provides exactly that. The Metrol B4 is a steel ball joint end fitting with an M6 thread, a 30mm body and a 8mm, 10mm ball. It screws onto the threaded end of the strut rod and clips onto a matching ball-stud bracket, so the strut can pivot freely through its travel. Its M6 thread suits a gas strut with a 6 & 8mm rod, and the 8mm, 10mm ball clips onto BRK-1, BRK-2, BRK-3, BRK-4. The ball sits on a M6 stud 13mm long behind the 30mm body, threading into the bracket socket side. Like every end fitting in the range it transfers the strut's force to the structure: a ball joint gives a connection that swivels in any direction, an eye a single-axis hinge, a clevis fork an in-line pinned joint, and a rose eye absorbs slight misalignment. It threads onto a gas strut with a 6 & 8mm rod, and is chosen by matching the thread to the strut and the size to the space behind the mounting. Typical applications include loft hatches, serving flaps, cabinet lids, access panels. Within the M6 range, its nearest sizes are B8, differing by body length.
