5641 Series Surface
Key Keeper Frames
The Bommer® 5620 and 5621 series key keepers are
designed for flush mounting. When flush mounting is
not practical or not possible, these key keepers can be
surface mounted using an optional 5641 series surface
The 5620 and 5621 series key keepers are U.S. Postal
Approved, and are required when mailboxes are in-
stalled behind a locked entry door. This allows the
Postman access to the mail boxes, without having to
bother (or wait for) any of the building's tenants.
These key keepers can be mounted vertically or
horizontally and include the mounting bracket and
screws for the installation of the postal lock (supplied
by the local post office).
We do recommend that before you surface mount any
key keeper(s) that you check with your local USPS
branch to make sure they will approve the installation.
