Rated 1 out of 5 by from Don't buy I have yet to see a Knaack latch & lock system last for any respectable length of time. No matter how many times they change it, it's still unacceptable.

Rated 5 out of 5 by from Customer for Life I recently received my 79-D and am really pleased with it. It is superbly made and holds some really heavy hydraulic equipment and the drawer is awesome. I own almost 20 of your boxes and the quality never ceases to impress. They certainly take a beating and keep going. I hope one day you will make a box with full length drawers like a 60" wide mechanics box built into a 139 without the center divider, that is my dream box. Thanks for continuing to make great products you have a customer for life!
