3.5.2 Width. Width of lumber shall be as specified on applicable drawings (See 6.10).
Variations will be permitted provided they do not exceed 1/8 inch for single un-jointed pieces or
Linderman-jointed pieces of lumber, fabricated as specified in 3.7, may be used. Pieces of
lumber may be butt-jointed or tongue-and-groove jointed to form an assembly. The type of joint
used in the assembly shall conform to the applicable drawing (See 6.10). All joints shall be tight
when fabrication of the assembly is completed.
3.5.2.1 Base or cover assembly. When the width of deck boards in the base or cover
assembly of Grade B pallets is not specified in the applicable drawings (See 6.10), the width
shall be the widest practicable for the assembly. A maximum of one-third of the boards shall not
be less than a nominal width of four inches.

3.6 Size. The length and width of the pallet units shall be as specified on applicable
drawing (See 6.10). Length shall be considered as the dimensions parallel to the skids. The
maximum length shall not exceed 62 inches and the maximum width shall not exceed 48 inches.
3.7 Linderman-jointed pieces. Individual pieces required in the construction of pallet
units may be formed by Linderman jointing narrow widths of lumber. Linderman joints shall
have two dovetail-shaped projections (tongues) along the edge of one member that shall extend
into corresponding recesses (grooves) in the edge of the adjoining member according to Figure 4.
The tongues shall be tapered from one end of the board to the other and shall fit tightly into
correspondingly tapered grooves. Width and depth of dove tails and grooves shall be in
accordance with Table III.
