Gang Plank Installation
For Mounting more than 4 MailBoss Mailboxes, use a Gang Plank!
When you need to mount more than 4 MailBoss locking mailboxes in a line, you have two options: (1) You can order additional MailBoss posts and spreader bars; or (2) You can mount these additional security mailboxes on a gang plank.
A gang plank is a level wooden structure that should be strong enough support, secure and protect as many mailboxes as can fit on its surface length. Many people attach roofs to these gang planks to minimize the impact of various environmental conditions on the surfaces of their mailboxes and the gang plank.
