Model 338-5 PACK RAT® Drawer Unit, 48 in x 40 in x 13 in is rated 3.3 out of 5 by 3.
Rated 4 out of 5 by from No organization extras So I'm an automation tech and this is an awesome tool and parts storage idea. I rated low on features because I can not find any sort of drop in tool organizers. If the company would come up with accessories to organize tools such as sockets, wrenches, and other hand tools this would put the company on top of the world.

Rated 1 out of 5 by from TOTALLY DISAPPOINTED I thought that this would be a great unit to store all my small electrical parts like the video says but when I received the unit I figured out that the cabinet size is 24" but the drawer size is only 21" deep and then to boot the drawer will only open 14" before it hits the stops, leaving the back six parts bins rendered inaccessible. Also the front center parts bin cannot be used because the locking mechanism is installed here and it would jamb if parts are stored in this bin. This means that 1/3 of the actual compartments in the unit cannot be accessed if you wanted to use all of them like I did. Should have been tipped off buy the poor video with the lady prompting the sales representative for answers that this would be a disappointing experience.

Interior of the drawer

what is the interior height of the drawer? In need to check if my equipment will fit. I assume the 12 1/2" dimension is the total height including the feet on the bottom of the box. I need the maximum clearance inside the drawer.
Asked by: Anonymous
Interior drawer height is about 10 inches

Can the drawer be completely taken out?

I need to get to the back side on the inside to put some bolts in
Asked by: Jeffro
You need to pull the drawer completely. There are two drawer tracks/slides on the left and right side being connected with rivets. you need to shear those 2 rivets on both sides to loosen the drawer. Once the rivets are loose, they can take out the drawer completely.

Do you custom build drawer units?

I am looking for a box that is 45" long x 40" wide x 15" tall. Your Model 338-5 PACK-RAT would work but it is too long. I can't be any longer than 45".
Asked by: Mark
We do not manufacture any custom sized boxes. For this we would recommend our 24" pack rat 301-3.
