4up W-2 Alternate Double Window Envelopes – Horizontal (Self Seal)

Alternate horizontal W-2 envelope, self seal

SKU 4356S is a self-seal double window envelope built for the alternate horizontal 4-up W-2 form, BW24DWNA — a slightly different window layout than the standard horizontal 4-up envelope. It closes with a self-adhesive latex flap and carries a tinted cellophane window on both openings to keep wage information private.

Fold the printed statement so the recipient’s mailing address falls in the top window and the wage detail falls in the bottom window, then press the flap to close. Because it’s matched to a specific alternate form, confirm your software’s print layout or request a free sample before ordering a full run.
