The Sanus comes with a "keyhole bolt/hand knob" fastener.
You adjust the Sanus arms to line up with the keyhole's in the playbar, hang on the included fastener, and tighten the hand knob securing the playbar to the arms.
I have given those to our techs to install, but never even opened one up myself, thanks!
