Metal Mounting Plate

Do you need some additional depth for the installation of your Mail Boss mailbox post? Do you prefer the sturdiness, security and strength of an all metal install? The Mail Boss Post Depth Extension is perfect for increasing the length of any Mail Boss steel mailbox post. The Extender is bolted inside the post at variable heights, and holes are pre-drilled at set distances of 3″ apart, allowing for a variety of installation heights. Optionally, at the bottom of the post depth extension there are 4 sets of aligned cross holes, which conveniently accommodate up to 4 sections of #4 rebar (1/2″ Diameter). Avoid measurements, save time, and shore up your install with the Mail Boss Depth Extension.
