parcel lock box

Protection varies by model. Common features include rainproof or all‑weather designs, built‑in drainage holes, rubber or foam seals/pads at openings, and explicit waterproof or weather‑resistance ratings on larger outdoor package boxes.

Common installation methods are: through‑the‑wall mounts (some models fit wall thicknesses roughly 2.8–7.9 in), through‑the‑door designs (for specific door thicknesses around 1.7 in), wall‑mounts using pre‑drilled holes, and outdoor bolt‑down or ground‑anchor installations for heavier parcel boxes.

Typical examples cover a wide range: heights from about 14.1 in to 41.5 in, widths about 6.1–17.5 in, depths about 11.4–17.5 in, and weights roughly 8.2 lb up to about 83 lb, depending on size and materials.

Many parcel lock boxes are made from steel; outdoor boxes and delivery bins are often galvanized steel for improved corrosion resistance. Product listings occasionally specify other metal finishes or coatings for weather protection.

Capacities vary by model. Small through‑wall or through‑door units typically list about 0.59–0.88 cubic feet, while larger commercial drop safes and parcel boxes are available in roughly 1.9–3.5 cubic feet.

Designs range by size: small through‑wall or through‑door boxes accept envelopes, smartphones and small parcels; larger parcel delivery boxes take mail, magazines and packages; commercial drop safes may also accommodate cash, documents and other valuables.
