Zoro Select M543 Literature Mailer

The Zoro Select M543 is a white literature mailer designed for shipping documents and flat items. It suits offices and mailrooms that need consistent, single-wall corrugated packaging in a compact format.

ECT-32-B single wall with B flute

The ECT-32-B single-wall construction uses B-flute corrugated cardboard with a 3/16-inch wall thickness. This structure provides a 65-pound maximum load capacity while keeping the mailer rigid and lightweight for everyday mailing.

Pack of 50 white corrugated mailers

Each pack contains 50 mailers measuring 5 by 4 by 3 inches inside and out. The 100-percent post-consumer recyclable material supports sustainability goals without additional certifications or standards.

Questions about this item

How do I assemble the Zoro Select M543 mailer and what step is often missed?

Fold along the scored lines, tuck the side flaps into the slots, and press the bottom panel until it locks; the step people skip is fully seating the bottom panel so the 3/16 in wall thickness aligns.

When will the Zoro Select M543 mailer need replacement?

Replace any mailer that shows crushed B-flute corrugations, torn corners, or moisture damage; the 100 percent post-consumer recyclable cardboard is single-use once structural integrity is lost.

What weight limit appears first when the Zoro Select M543 mailer is used repeatedly?

The 65 lb maximum load capacity is the first limit reached; exceeding it causes the ECT-32-B single-wall construction to buckle under sustained stacking pressure.
