How To Re-square a Drawer Box

How To Square or Re-square a Drawer Box

During production and assembly, our drawer boxes are put through a drawer box clamp, which not only presses the dovetail joints into position, but also precisely squares the drawer at the same time.  The use of this type of precision equipment insures that your drawer boxes are perfectly square when they leave the production facility.

Even though your drawer box leaves the factory perfectly square, the shipping can sometimes be a bit rough and your drawer boxes can be jarred "out of square" during shipping.

Here are a few easy to follow steps for "resquaring your drawer box"

Gather what you need

Gather your drawer, tape measure and mallet
Get your drawer box along with a tape measure and if you have one, a mallet

Prepare and measure

You will be measuring opposing corner to corner
You will be measuring opposing corner to corners
Take first measurement

Take your second measurement


If your drawer box is out of square, you will have different measurements for the lengths of the opposing angles.  If your box is square, your measurements will be the same and no adjustment is necessary.  If your measurements are different and you want to resquare, then proceed to the next step.

Perform the adjustment

Stand drawer up with longest side vertical
Stand the drawer up on solid surface (take care) with the longest side being vertical
Tap the upper corner to adjust the length of the side
Tap/knock on the longest side and then recheck the measurements, repeating process as needed

This should be sufficient for solving just about all "out of square" situations and will save you both time and expense versus replacing drawer boxes.
