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. 

With their oversized drop opening, this postal approved curbside mailboxes can accept parcels up to 6 inches thick, 10 inches wide and long - plenty of room for large envelopes, boxes and bubble mailers. The internal baffle prevents fishing and theft while allowing easy front access for USPS or parcel delivery drivers.

Customizable in multiple durable powder coated colors including black, gray and custom shades, these heavy duty mailboxes make a bold statement. Available with in-ground or surface mount post option, they bring reliable package acceptance to homes, businesses, offices, or retail locations.
