The product arrived on time and it was easy to install. I recommend that at the time of installation consider that the material of the lock is weak so you can easily damaged it if you apply to much pleasure to it. Quality correspond with value of the product.

This fits the Reliant / Gibraltar lockable mailbox commonly found at big home centers. My rotating arm on the old lock was peened over and had worked lose after someone tried to break-in. Looking for an improved version the 4573 has the rotating arm bolted to the lock body. Far more robust. In addition, the key retention feature holds the key in the lock when in the open position, so your keychain doesn't fall in the snow as you are trying to retrieve your mail. A big weakness in the original lock. Only minus is that the lock is rotated 90 degrees from original with key removed. See picture. Easy install. Good value. Would buy again.

While opening my mailbox one day, I broke the key off in the lock. The lock was old and janky anyway; I ordered one of these to replace it with. I chose this lock because the key looks the same as the key from the old lock. For lock replacement, installation was simple: simply remove the old lock, match the locking arm on the old mailbox lock to one of the five included with the set, and fasten the lock to the mailbox using the two included nuts. (A screw was alluded to in the instructions, but the actual device uses a nut instead.) It took about five minutes, including the walk to the box from my apartment and back.As compared to the old, dirty lock that this one replaced, it opens much more smoothly and reliably yet still feels very securely fastened to the door of the box. That said, I am not terribly concerned about the absolute security of this lock: if someone wanted to steal my mail, they would be much more likely to jimmy open the postal lock that opens the whole box at once. This is an easy DIY solution to a common problem that locksmiths or the post office would have charged dozens of dollars to fix.
