Letters go through the 8.5-in x 0.8-in slot at the top while parcels are locked into the 12-in x 15-in x 25-in compartment below, keeping mail sorted without a second fixture by the door. A coded lock covers the mail section and two keys open the parcel door, so a courier can deposit without any access to what is already inside. The 13-in x 17-in x 44-in column is galvanized steel with PVC and zinc alloy hardware, powder-coated against rust, and each compartment holds 110 lbs. A shock-absorbing cushion drops into the base to protect fragile deliveries. The unit weighs 34 lbs and can be anchored down; screws and a pair of gloves are supplied with the instructions.
