Rightline Gear Adjustable Cargo Bar, 43"–75"

A cargo bar keeps loose items from sliding to the front of the bed, and this one adjusts across a wide enough range that it will fit the Fathom regardless of how wide the bed turns out to be. Note the brand now lives under Klymit after an acquisition, and that some retailers list this same part with a narrower 40–70 inch range than the manufacturer states. No load rating is published, so treat it as a divider rather than a restraint.
