My crew and I simply fell in love with our Clamtainers. We put screws, nuts, bolts, wire nuts, you name it into them and close it with one hand and then open with one hand. We toss them into our tool belts, behind the truck seat, into the tool boxes, everyplace. One of the best things is they don’t fall apart in wet weather when we get rained out and leave screws and such on the job site. No more mushed broken boxes and rusted hardware.Jeff FortnerOwner – Fortner Construction
