Clockwise or counter looking at the panel?

The MIT RCA barrel has two parts - stationary and rotating. The stationary barrel is to the rear, closest to the cable jacket. Both barrels have knurled grips. To remove, hold the stationary barrel firmly and turn the front (rotating) barrel by the knob counter-clockwise (looking down - right side up left side down or clockwise from the back). The rotating barrel will travel rearward towards the stationary barrel until it stops against it and the gold locking clinch is visible around the units' rca plug. Now it can be removed.

To install, make sure the RB is fully back where you see the clinch. Place on the jack while holding the SB and push firmly towards the unit until it stops. Turn the RB clockwise while continuing to apply pressure towards the unit as it locks (or else it might slide off as the clinch is tightening).

let me add another warning. as most people have said, mit's locking clamps work in reverse. you hold the stationary part, and rotate the moving part clockwise, and it will travel back towards you. HOWEVER, some of those damn cables can still be quite stuck on, even in the loosest position. you can yank the connection right off your amp or preamp if you're not careful. you have to kind of walk it back off still. and of course, MIT makes cables that don't have locking clamps, that just have your standard tightening mechanism like all other cables. if you're dealing with one of those, it's back to cfb's rhyme. the new 330 series has the locking clamps. the terminator series is like other cables.

Thank you all for your input. Tried it last night. Clockwise it was.
