Are you really trying to compare a 500 dollar box's slides to a 5000 dollar box's slides? I wouldn't expect the harbor freight slides to be anywhere near the snap on slides! I'm sure they are comparable to other boxes in the same price range. You have to decide what quality box you need. If you need slides that will hold hundreds of pounds then spend the money on a snap on box. If you only need slides to hold a hundred pounds or whatever hf rates them at then the hf is a decent box for the money. But you cant honestly compare hf slides to ones that cost ten times the cost.
well, kinda. ya have to compare it to something .
no, i am not expecting the $799 box to be as good as a $4000 box.
but actually, for the money, if not overloaded, its BETTER than a truck box.
