Salisbury Industries of Los Angeles Manufacture The Highest Quality Mailboxes

There are literally thousands of mailboxes that are available on the market. Many are of excellent quality, some of them poor.

Most of the mailboxes offered by the various manufacturers are not lockable and secure. These mailboxes are not suggested for security purposes.

Very few secure, locking mailboxes are of excellent quality and also pleasing to the eye.

We have found that the highest quality and most attractive are made by Salisbury Industries of Los Angeles, Ca. (

Salisbury has been in business since 1936; they manufacture amongst the highest quality mailboxes in the world.

Our Recommended Salisbury Locking Mailboxes

This is our most popular model.  It is available in green, black, silver and white powder coated finishes. Its dimensions are 12.5” wide by 13.625" high by 18.25" deep.

It’s made entirely of aluminum. It is very easy for you to get your mail out – both from the front and the back – but a very difficult problem for a thief.  The thief is looking for the easy targets in your neighborhood; not the strongest mailbox on the block!

Same design and color, but a bit bigger:

This looks just like the model pictured above, and is available in the same colors, but it is about 15% bigger.

It is perfect if you subscribe to a lot of the large format periodicals. Its dimensions are 14.375" wide by 17.25" high by 23" deep.

For Smaller Homes with less mail:

There is another model that is quite popular, the model 4750. It is popular with people who want a smaller appearance for their mailbox. Its dimensions are 17" wide by 15" high by 8" deep.  This is actually big enough for most of the largest periodicals, but it isn’t very deep.

Don’t Forget The Post!
