The beauty of the positive and negative ratcheting feature is that you don't need to really crank them down hard on the glass--just barely tight. The ratchet mechanism is rated to +/- 40G, so it won't come loose, and it doesn't dig into the glass--therby obviating the need for washers (working and flying great for 5 yrs this month). I also nearly had a heart attack at the price, but I guess quality costs in the short run. What I DID do was modify my cowling installation so that I only used 11 of the units. How? I use piano hinge along the lateral seams and over the top rear of the cowl, and also vertically along the rear seams of the bottom cowl. I used the Tridairs around the spinner area, an external power unit door on the upper cowl, and around the acute curves at the rear lateral aspects of the top cowl as the seam transitions from horizontal to vertical.
