Closed-back 48-inch steel mail sorters are the perfect office furniture mailroom managers use to keep their workplaces organized. Stable after being set up on a table or countertop, our mailroom sorter shelves are a sturdy solution for mail sorters who go through hundreds of papers.

    • Mail sorters are formed and welded all-steel construction
    • Each mail sorter shelf is adjustable by ½” increments
    • Sorters are available in grey or putty finish
    • Most sorters are available in either 12 ¾” or 15 ¾” (legal size) mail sorter depth (there is an upcharge for the 15 ¾” sorter depth)
    • These solid steel mail sorters are perfect for production mail centers or for the office environment
    • Mail sorters feature two different individual shelf widths - 9 ½” or 11 ½”
    • A ½” shelf identification lip is located on the front edge of each shelf for easy labeling
    • Unlimited combinations of these mail sorters and our large collection of mailroom tables can create the most efficient layout for any mail center.
    • The exclusive modular design is an all welded construction sorter shell that interlocks as you stack them, giving you more individual component options when your mail center changes or expands.
    • Combine with our adjustable height tables and mail carts for an efficient mail operation.
    • Shelves and sorters are finished with baked on enamel, powder coated and formulated for chip and corrosion resistance.
    • Don't forget to order removable shelf labels for your new mail sorter! Available in 3" long x 1/2" high size (box of 25). See product number L22 at the bottom of this page.
    • Do you need additional or replacement shelves, vertical shelf supports, pocket bins or other accessories for your mail sorter? Just follow this link to our convenient sorter accessory page.
    • The Mail Sorters shown on this page are not manufactured to be hung on a wall - they must be fully supported underneath either by resting on a table top, shelf, placed on the floor, etc. Mail Sorters may optionally be fastened to the wall through the back of the unit at the customer's discretion for added stability.
    • Multi-tier Mail Sorter "shells" nest on top of each other, so it is not required to bolt them together. However, small bolt holes are pre-cut into the top and bottom of each Mail Sorter shell at all four corners, so the customer may fasten them together using small nuts and bolts (not included) for added strength and stability if the customer so desires.
