3. When sides, ends, tops, or bottoms are made of more than one piece, the pieces must be tongued and grooved and glued, and the joints in making up the boxes must be staggered.

4. All lock and dovetail corner joints must be glued.

5. Nail driven through sides, tops, and bottoms into ends must be not greater than 3-inch centres for boxes not more than 12 inches in width, and at not greater than 4-inch centres for boxes of width greater than 12 inches.

6. Nails driven through top and bottoms into sides must be at not greater than 6-inch centres. Nails through the top or bottom into sides are not required when thickness of sides is less than inch.

7. Gauge of nails used shall be not less than the following sizes, depending upon the thickness of lumber into which they are to be driven:—

3-penny into 3/8 inch lumber.

4-penny into 7/16 to 1/2 inch lumber.

5-penny into 9/16 to 5/8 inch lumber.

6-penny into 11/16 to 13/16 inch lumber.

7-penny into 7/8 inch or thicker lumber.

For example, nails driven through a 1/2 inch side into a 3/4 inch end must be 6-penny. Screws of equal efficiency may be used in place of nails.

8. When boxes are set up, the bottom and lids must fit evenly on the frame.

Marking

9. Each box must be plainly marked with a symbol consisting of a rectangle, as follows:—

C.R.C.—14

The letters and figures in this symbol must be at least 1/2 inch high.

This symbol shall be understood to certify that the package complies with all the requirements of this specification.

When offered for shipment the package must also bear the wording prescribed by these regulations for the particular article contained therein.

Thickness of lumber

10. Thickness of lumber in the finished box must be not less than the following:—

10 (a).

Ends Sides Top and bottom
inch inch inch
For nailed boxes 1 1/8 5/8 5/8
For lock or dovetail corner boxes 5/8 5/8 5/8

The thickness of the ends of nailed boxes of over 75 pounds gross weight may be reduced to 7/8 inch if they are cleated with two vertical cleats and two horizontal cleats not less than 1 7/8 inches wide and 5/8 inch thick, and in this case the sides, top, and bottom must extend over the cleats, and the nailing must be staggered, at least 40 per cent of the nails being driven into the ends and at least 40 per cent into the cleats.

Additional nailed and cleated wooden box

11. (a) These boxes must be constructed and marked in accordance with paragraphs 2, 3, 8, and 9 of this Specification, and as follows:—

(c) Boxes must have two vertical and two horizontal cleats on each end, nails fastening cleats to ends being staggered. The sides, top, and bottom of the box must extend out over these cleats. Cleats must be of 1/2 inch lumber 1 1/2 inches wide.

(d) Sides, top, and bottom must be secured to ends with nails as specified, driven into the cleats and not into the end boards. To determine the minimum number of nails to be used for fastening sides, top, and bottom to ends, divide the width of the sides, top, and bottom respectively in inches by 1 3/4; for fastening cleats to ends, divide the length of cleat in inches by 1 3/4; fractions greater than 1/4 in the results will be considered whole numbers.
