XL Heavy Duty Large Steel Locking Mailbox

Introducing the XL Heavy Duty Large Steel Locking Mailbox - Keep Packages & Mail Safe and Secure!

Our heavy duty steel parcel lockboxes are designed for maximum security and weather resistance. With their vault style baffle and reinforced steel door, this high capacity mailbox keeps packages and mail protected from weather, and thieves.

Fabricated from 1/4 inch thick steel and hand crafted in the USA, the vault style mailbox is as sturdy as a bank safe. Continuous welded seams and solid steel hinges ensure this high security mailbox will never sag, warp or bend even in extreme weather conditions. This mailbox is made with heavy duty 3 gauge (1/4") steel.  1/4” steel (3 gauge) is more than 13 times stronger than 12-gauge. 12 gauge is more than adequate for most mailbox needs and many of ours are made from 14 gauge, so if you buy this locking mailbox made from 3 gauge steel it is 13 time more stronger than most home safes which are made from 12 to 14 gauge steel. 

Additional charges may be needed if shipping to a residence.
