Works perfectly and it matches the rest of the locks
I removed my old lock and put this one in and it appears to be the exact same quality and look as the original one. It was easy to install and it matches the rest of the locks perfectly. It doesn't stand out at all.

Perfect replacement for Salsbury Industries 3390 Standard Replacement Lock for F Series CBU door
Perfect replacement for Salsbury Industries 3390 Standard Replacement Lock for F Series Cluster Box Unit Door with Three Keys. I did have to use the leaver/latch from the old lock, but everything fit and worked perfectly.,... a 5 minute replacement.

Much easier than expected
The unit replaced an older lock. Was a surprise at ease of installation. Just needed either an adjustable wrench or else pliers. A flat edge screwdriver helps in prying off the old one.

Lost our key from our mail box and bought this to replace
We lost our keys from our mailbox and had to replace it and it would’ve costed us $200 to have the locksmith to come out and do it so we ended up buying this lock and changing it ourselves. The lock fit perfectly so glad we were able to find this.

An Easy to install, Perfect solution for our Florence 1570 Cluster box lock & key replacement.
We moved into a new complex & the previous folks took the mailbox key with them. I took the time to look at the brand of cluster box that housed our specific "mailbox" & looked into options on their site. Ours is a Florence 1570. After double- & triple-checking myself I ordered this lock & key combo. Once the small package arrived I spoke with my mail carrier & she opened the main cluster box door to allow me access to my slot & lock. The swap only requires 2 tools, channellock pliers, & a 1/2-inch nut driver (or a wrench or something similar). The swap, when you're prepared, only takes a couple of minutes so you don't have to hold up your carrier. I was actually a little worried because it went so easily, but everything works like a charm. We have access to our box, 3 keys, & peace of mind that only we have access to our mail now.
