This product is well made out of heavy gauge steel , and holds my 4 maxtrax very solid . Only improvement I can recommend is some kind of 1/4 turn twist , and lock system that would let you easily remove the brackets when not in use . The maxtrax pins look kind of funny , unless you store your maxtrax on them all the time . Having to remove 12 bolts , 12 nuts , and 12 washers every time after a trip is gonna be kinda tedious , and there's the risk of losing hardware . Otherwise , I think this is the best system to mount maxtrax on your roof rack if you wanna keep the weight to a minimum.
