• The weights used in the test were steel plates 8" x 17"
• Each plate weighed 5.12 pounds.
• The plates were stacked one on top of the other in the locations shown.
• A "hanging" scale was attached to the drawer pull on the front of the drawer to measure the pounds of force to open the drawer and to keep the drawer moving at the distance shown.
• The Toolbox was mounted on a level test table. The results in the lab should be similar to the results in the fields, the back of a level pick up truck.

How the Data Should be Interpreted

• This test was done in controlled conditions.
• The weights used were steel blanks. It is unlikely that you would be carrying materials as dense as these steel blanks.
• The model tested was a 72" box. Similar results will be obtained on other models.

Facts About the HD Roller System

• The drawer rides on 3 or 4 sets of wheels mounted on the frame of the shell.
• There are 2 wheels at the back of each drawer that ride on a channel mounted on the shell.
• As the drawer is opened, the front of the drawer may tilt down slightly, until the wheels riding in the channel become top bearing, instead of bottom bearing.
• As the drawer is opened, the drawer is supported by fewer wheels. The further you pull the drawer out, the more concentrated the load on the wheels become.
