Allstar Performance ALL10219 Spring Loaded Round Tube Type Window Net Installation Kit for Border and Loop Style Nets

These products look asas good as pictured. They're not so great for window net mounting, since they require a good bit of clearance all the way around, but they make an AWESOME camera mount (the supplied bolt in one fits most camera mounts) or harness stop.

Heavy duty quality product

Ok.

If you have a window, i really do recommend one of these ... have fun... speed safe !!!
