Hey everyone

Well I had a old tool box on a 1990 F-150 I had and of course I drilled (2) 1/4 holes on each side about one inch from end of tool box held for years..
----

So i bought me a new tool box for my 97 f-150
A Better Built tool box,, and I like it but it has a new system i have never used before called Grip Rite a system that uses no Drill mounting system...
They have pre-punched knock-outs for each side about 4 on each side,and their hard as heck to punch out ....
so anyway they give you the rubber strips to place on your rail to prevent squeaking and all that ...It says to punch (knock-outs) half way out and put the strips on the rail so i did that....now it's time to place the tool box on the stips with have only one sticky side and that side is stuck to the bed rail..i can't knock the pre-knock out holes out at all their not cut enough...i even tried to drill the sides with my drill with no luck......so what in the heck are they talking about????and even if you get the pre-knock-outs out i don't understand how that helps because it says knock them out and bolt to the strip but it says this is a Grip Rite system that uses no drilling????
I got some of that double sided strong tape you use to put antinas on your windows and that stuff is strong...so i put two nice pieces on the black strips and that baby is so damn strong I couldn't pull it off at alll......so do ya'll think that is safe???? because i really have no ideal what Better Built is trying to tell the buyer of the tool box to do as far as mounting the box?????
