Airline Travel Kit: Airline rails are required on all crates when shipping an animal by air. They guarantee an air space between the crate and other baggage. Kit includes 2 rails compatable with all Zinger dog crates. The package also comes with extra security lock covers, side handles, bowls, and Live Animal stickers to meet airline guidelines and requirements.
Heavy Duty Handles Only: Designed to be tough and last a lifetime. Built-in spring keeps the handle from rattling against the crate wall. Fit all Zinger dog boxes and can be retrofitted to most aluminum crates. (already included on all Zinger "P" models)
