Its steel construction with a rust-proof powder-coated finish is built for durability, while the code lock and internal metal baffle help protect contents from tampering. The rainproof flap plate, rubber mat, and drainage holes are designed to improve moisture protection. The adjustable chute fits doors up to 1.77" thick, and mounting hardware is included for installation.
