Very easy! Tools needed are a drill, 2 drill bits (1/4" & 9/64"), Phillips screwdriver, and a couple 7/16 wrenches. Just drill 3 holes, some minor assembly is required & bolt on. Directions are included in shipping tube. Please note: Some small parts are included in the plastic bag!
Standard kits are for typical "barn shape" style metal mailboxes but, these have different depth's compared to different sizes of height & width. Indicate depth of mailbox from front door to rear wall. Clearance around rear exterior of mailbox needs to be 9" around upper half and extending that 9" a further 6" from rear of the mailbox. For plastic, custom & unique mailboxes, e-mail dimensions, preferably with pictures & I will contact you about suitability.
