The Mail Boss Triple Mail Manager package puts 3 locking curbside mailboxes on one post. It suits duplexes, townhomes, rentals and shared driveways where each household needs its own secure box. Each mailbox takes letters, mail bundles and small packages through a baffle door that stops mail fishing, and only the key holder can open the retrieval door.

- USPS approved for curbside delivery (Standard 7C). Check with your local postmaster before installing.
- Commercial grade 12 disc high-security wafer lock with a patented anti-pry latch
- Baffle door accepts mail bundles and small packages up to 3.5" H x 10.2" W but prevents fishing
- 14 and 16 gauge electro-galvanized welded steel with stainless steel hinges
- 3 keys and a vandal resistant flag with each mailbox
