Buying Guide
Locking mailbox posts keep your mail safe from theft. They add strength to your setup.
Years ago, I tried several mailboxes at home. Lockable posts stopped tipping and kept thieves away.
– Material: Choose posts made of heavy-duty steel. Steel lasts long and feels strong. Avoid options with weak parts.
– Durability: Pick posts that handle weather and time. Tough finishes fight rust. Solid builds prevent easy breaks.
– Locking Security: Add lock posts to stop theft. High-security locks are hard to pick. Baffles block mail fishing.
– Compatibility: Check if the post fits your mailbox. Some work with all Mail Boss models. Others match specific designs.
– Installation Method: Select posts for in-ground or concrete mounting. Bolts make setup quick. Kits include all hardware.
– Size and Dimensions: Get the right post height for your home. Large posts hold big loads. Width fits curbside rules.
– Weather Resistance: Posts need to stay dry and safe. Coatings block rain and sun. Steel endures all seasons.
– Included Accessories: Kits often add keys and clips. Hardware comes with bolts. Tools help simple builds.
