I traded another rest for this one,looks to be in great condition it is black in color,looks like it would work great for containment,looks like the little rubber bumper under the launcher has been shaved down for better clearance,very quiet too.Since i use a WB i really have no need for this one.
Asking $50.00 tyd,no paypal,money order only,postal money order prefered,thanks for looking.

does it have the clamp to clamp the string to the bus cable?

No it doesnt,when i tried it on my bow i just split my downcable then served it in,i never use those little clamps.
You can get those clamps pretty cheap at any online store or proshop.

Any offer's..............Also would consider a trade for a single pin slider sight.
