Use the Base Mounting Anchor Kit for Courier Collection Box from National Mailboxes to securely anchor your Courier Box to new cement. The J-Bolts included in the kit need to be embedded in newly poured concrete while it is still wet. The “J” shape makes it so the bolts will never slide out of the concrete for a long lasting installation. After the concrete has set up, the Courier Box is securely attached to the J-Bolts using the included nuts and washers.
