Riopel Mailboxes have, by far, the widest range of standard and custom chutes for mail, packages and other items. Most chutes are made from 1/4" aluminum plate with .050" thick stainless steel tray but we also offer chute doors and frames in polished stainless steel. Chutes can be lockable or with post office lock. Please see the full range of chutes, dropboxes and mailsafe mailboxes on the Riopel full line website.
