The listings include compact through-wall/through-door units and larger parcel boxes. Reported internal capacities include about 0.59 cu ft and 0.74 cu ft. Exterior dimensions range from roughly 14.1 x 6.1 x 12 inches up to about 34 x 17.5 x 17.5 inches.

Slot sizes in the listings range from about 1.6 x 9.8 inches up to about 1.9 x 10.2 inches. These openings are described as suitable for envelopes, smartphones, and other small parcels.

The products are primarily metal: steel (including rust-resistant and powder‑coated finishes), galvanized steel, and cast aluminum are all represented, along with other metal constructions.

Listings show both combination-style (keyless) locks and traditional keyed locks. Some products include supplied keys, while others use built-in combination mechanisms for keyless access.

Listings describe several weather-protection features: over-slot shields or flaps to block rain, drainage holes and rubber pads at the bottom, and weather-resistant finishes such as galvanized or powder‑coated steel to keep contents dry.

The selection includes through-door designs, through-wall (wall‑mount) models, and floor‑standing/bolt-down parcel boxes for higher capacity installations.

Through-wall drop boxes with adjustable slides are compatible with wall thicknesses from about 2.8 to 7.9 inches (70–200 mm). Through-door designs are described as compatible with doors around 1.7 inches (43 mm) thick.
