How to Assemble a Cabinet Box

Assembling a cabinet box is a fairly quick project that is not as complicated as you may think. This guide will provide you with all the information you will need to construct your cabinet box and help make the process as easy as possible. Here are the materials you will need that are not included with your cabinet box:

  • Materials:
    • Wood Glue
    • Staple Gun with ½” staples
    • Finishing nails and hammer

A staple gun is recommended for ensuring the stability of the cabinet box as it allows for a fast assembly and tends to be more accurate. Finishing nails and a hammer are another option, but the risk of missing the nail and damaging the cabinet box makes this a less ideal decision.


Before you get started, make sure you have all your cabinet parts:

  • 1 Face Frame ‒ Large, front piece with openings for cabinet doors and drawers.
  • 2 Sides ‒ Tall pieces that have grooves located on two edges for connecting to the Frame and Back. They are labeled left and right and have a cutout to fit the toe kick.
  • 1 Bottom ‒ This piece is approximately the same size as the side pieces but without the cutout.
  • 1 Back ‒ The same size as your Face Frame, but will have a closed center.
  • 1 Toe Kick – Has a groove down the center and one on each side.
  • 2 Top Spreaders – Long thin pieces that will rest on the top of the cabinet box.
  • 1 Toe Kick Spreader – Will be placed in the middle of the toe kick for added support.

Each piece is labeled with its position. Be sure to check the labels before beginning assembly.

Cabinet Box Pieces

Protect your Surface

Working with wood glue can get messy. To avoid getting glue on your work surface, we recommend opening the cardboard box your cabinet box came in and using it as a protector for your surface.

STEP 1: Connect the Frame to the Sides

  • Separate the frame and side pieces, as they will be assembled first.
  • Position your frame with the notched side facing up.
  • Carefully apply your wood glue down both sides of the face frame notching area.
  • Slide the sides into the notching areas. Be sure to match the proper sides with the correct notches, keeping the toe kick at the bottom of the frame. Wipe away any excess wood glue.

STEP 2: Add the Bottom to the Frame

  • Apply wood glue along the bottom notching of the side pieces and along the bottom notch of the face frame.
  • Then, carefully slide the bottom piece in along the notching and wipe away excess wood glue.

STEP 3: Place the Back Piece

  • Carefully apply wood glue along the edges of the bottom piece and both sides.
  • Lift the back piece making sure the notching on the back line up.
  • Place the back piece down and fit the side and bottom pieces into the notching on the back piece and wipe away excess wood glue.
  • Tack down the back along the side pieces, bottom, and top to add support to the structure.

STEP 4: Fitting the Toe Kick

  • Gently turn the cabinet box over so it is lying on its back with the frame facing up.
  • Apply wood glue along the middle notch on the back piece, located on the toe kick.
  • Locate the toe kick spreader and insert it in the middle notch and wipe away excess wood glue.
  • Carefully apply wood glue along the exposed edge of the toe kick spreader and the side pieces.
  • Tack the sides to the toe kick. Line the toe kick notches up with the glued edges and fit the toe kick into place.

STEP 5: Add the Top Spreaders

  • Now stand the cabinet box upright.
  • Apply wood glue to the notching on the top of the back piece and the notches on the side pieces.
  • Fit the notched top spreader onto the glued back notching.
  • Finish the cabinet by tacking the spreaders into the sides.
  • Apply wood glue to the notching on the sides, near the frame, and fit the other top spreader into the notching. Wipe away any excess wood glue.
