Door ID Option

(STANDARD) Cardholders are a type of door identification for the 3600 series horizontal mailbox that includes a 2"W x 5/8"H clear plastic holder and card for each compartment door. The card can be marked by you in the field to identify each door how you want.

(+$40.00) Custom engraved placards are self-adhesive and measure 2"W x 0.625"H x 0.25"D that can be custom engraved as you specify.

(+$70.00) Custom engraved door identification for the 3600 series horizontal mailboxes can be customized according to your requirements. Custom engraved door characters will be silver in color because 3600 series horizontal mailboxes are fabricated from aluminum.

(+$70.00) Custom black filled engraving is viewed by many as the most attractive door identification option. The mailbox door characters are engraved to your requirements and then each character is filled with black ink to accentuate the door identification.

Access Option     

(STANDARD) USPS access means that the mail receptacle will be used for U.S. Mail delivery delivered by the Postal Service. In this case, a master door or cover will be prepared for the postal master lock which the USPS will install in the field typically at no charge.

(+$35.00) Private access signifies that the receptacle will be used for a private application. In this case, the master door will be equipped with a commercial lock.  

Load Type

(STANDARD) Front loading horizontal mailboxes require one door to be reserved for master entry by the delivery agent.

(+$375.00) Rear loading horizontal mailboxes do not require a door to be deicated for master access because master entry is gained through the back of the module. All openings are usuable for rear loading units. Units include a removable rear cover.
