fellas, what i do is there are two holes for the prussic side. i do two overhand figure 8 knots(overkill) on the bottom side. undo the knots, rope comes free.
i did rig it with a carabiner, but found it made a lot of noise bumping it. [/QB][/QUOTE]
you know you could put two bigger holes about an inch from the smaller ones with a 3/8" strip removed which will act as a tract that connects both holes then just leave a knot on each end of rope just big enough to fit through the big holes but then you slide the knot through thse 3/8 sections they will lock under the smaller holes,, now its just pop-thru and slide.
when you build more leave out the smaller holes and the track it self will keep the knots from coming through..
