Stud Bracket on Operator Arm

Hello! This part is called a "detach clip." Its function is to lock the operator arm onto whatever bracket stud it attaches to; most operator arms just have a simple hole at the end, so there's nothing to actually secure it to the stud. That's where this clip comes into play: it pushes forward to snap over the stud, which connects the two pieces firmly together.

Hopefully that makes sense. Yours in particular appears to be a match for our 39-558.
