It would help to have better photographs of the parcel box 300 showing the construction before making a decision on purchase. There is no strengthening of the back panel to allow for bolting to a wall or pillar. The "security" drop flap that lowers when the lid is closed to drop mail into the box is easy to get hold of by lifting the lid and can be forced up to remove and steal any mail. The side struts are not strong enough to resist theft. The drop flap has quite a large gap between it and the walls of the box, so theft of mail is relatively easy with a coat hanger or other tool. Overall, not that impressed. Good quality finish.
