#10 Window Envelopes for Postage Meters

These #10 window envelopes measure 4.125 by 9.5 inches and come in a box of 500. They are designed for postage meter use with a poly window positioned four inches from the left edge and two and a half inches from the bottom.

Check Window Placement and Paper Weight

Verify that your postage meter or inserting equipment matches the 1-1/8 by 4-3/4 inch window size and location. The 24-pound white sulphite stock with vellum finish feeds through most standard machines, but confirm your device accepts diagonal-seam construction and remoistening seals.

Suits High-Volume Mailings, Not Custom Sizes

Offices sending 500 or more metered letters per box will appreciate the SFI-certified 92% brightness paper and bulk carton option of 2500 envelopes. Buyers needing non-standard dimensions, tinted security lining, or peel-and-seal closure should look at other envelope styles.
