Replaces Single-Window Mailers

The top window sits 5/8 inch from the left and 2-13/16 inches from the bottom at 13/16 x 3-3/4 inches. The bottom window measures 1 x 4 inches positioned 5/8 inch from the left and bottom edges. This layout handles dual-address forms that single-window versions cannot accommodate.

Questions about this item

Will the 4.125 x 9.5 inch dimensions fit standard #10 filing systems?

Yes, these measure exactly 4.125 by 9.5 inches, matching the standard #10 size used in most office filing equipment and mailing machines.

How do I seal the remoistening flap without it sticking prematurely?

Apply moisture only along the gummed edge using a damp sponge or envelope moistener; avoid wetting the white wove body so the seal activates cleanly when pressed.

When should I replace the box if the windows start to cloud or tear?

Replace the stock once the 13/16 by 3-3/4 top window or 1 by 4 bottom window shows fogging or edge splits that obscure the 5/8-inch offset addresses inside.
