The handle is made of 1" PVC with a cap on each end. The total length from the tip of one cap to the other is 9.5". Just inside the cap on each end there is a hole drilled into the body of the handle where the rope enters one end and then returns out of the other hole. I am not sure if the line is cut off and knotted inside the handle or it is looped through one hole and out the other. I suspect it is knotted because I cannot slide the rope through the holes. Short distances from where the lines leave the handle the two lines come together and are nicely braided all the way to the other end where the lines are separated again and they form a small loop. The distance from the tip of the small loop down to the center of the handle, where you step on it, is 47". This guy sells them in two lengths and I believe I have the longer length, but I am not sure.
He did a nice job making these and I am not affiliated with him in any way. I just found this on eBay one day. He even has a Youtube video of how it works. http://www.youtube.com/watch?v=uRd1ha2r ... e=youtu.be
I pass the smaller loop around the leg of the advantage seat and then pass the handle through the small loop to secure it to the seat/boat. I coil the extra rope around the handle and place it under the seat so it is out of the way.
I hope this helps.
