I borrowed a harness to use while I was waiting for my Dudek Powerseat to arrive. It finally arrived an now that I have it hooked up I thought I would share how I did it. I sanded the slots really good to prevent the straps from wear but I still don’t want the straps sliding around so I routed the straps in such a way to create a hinge rather than sliding around through the slots. This was done by going through a single slot in the front plate and both slots in the back plate. Not only does this “hinge” method protect the straps but it helps the unit to fold up nicer.
I added an extra strap to one of the bottom straps so that I can connect the two together. Now I only have to do up one buckle instead of two for easier setup.
