"The GrayDoor Mailbox locking system has added a huge sense of security for me and my wife knowing that our mail cannot be tampered with or stolen once delivered. We ordered the device and it was installed promptly. GaryDoor is one of the most useful inventions and since such a large amount of identity theft happens at the mailbox level, this product allows everyone to do thier part to keep from being a victim. We are very pleased with the Graydoor product and your company."

"Is your mail secure when it is in your mailbox? Mine wasn't, but it is now! Over the weekend I installed a residential mailbox locking system. Harry Kalenberg invented a mechanism to deter thieves from stealing mail out of your mailbox. The device fits inside standard mailboxes and there is a slot so the mail carrier can insert the mail, but a key is required to open the box and remove the mail. Peace of mind = Priceless!"

"The GrayDoor is the best invention in the history of the mailbox! I could tell by the NBC interview what an honorable man you are and after viewing your Clear Expression website it is evident that you are extremely creative as well. It was truly a pleasure meeting you. Thank you for serving our country, and thank you for continuing to make it a safer place."

“Mr. Kalenberg sells a wonderful product called the Gray Door, which is an insert that can be riveted into an existing mailbox that turns the mailbox into a lock box that requires a key to open. Harry provides two keys to the mailbox locking system and it is a wonderful mail theft deterrent, which reduces a person's risk of identity theft.
Shortly after having mine installed the mail was stolen out of many of my neighbors mailbox. My mail was found safely behind my "Gray Door!"
Thank you Harry!!!”
