Carry and protect a Gibson 335 in a molded case with an instrument-specific interior profile for the body and neck. The iSeries construction uses a molded plastic shell, plush lining, molded-in hinges, and a gasketed watertight seal. Its 49.5 x 21.5 x 9 in exterior encloses an instrument up to 44.5 in overall length, with support for a 21.5 in body length, 4 in body depth, and 16.3 in body width. Recessed quiet-glide wheels and a snap-down rubber overmolded grip handle make the case practical for moving a semi-hollow guitar through venues, airports, rehearsal spaces, and storage areas. A pressure equalization valve supports travel through changing ambient pressure. Trigger-release TSA latches close the case, while four reinforced locking loops accept user-supplied padlocks when additional security is required. The 3I-4719-35 differs from a general-purpose instrument case through its Gibson 335-specific molded support and lid space for a Bigsby vibrato tailpiece. Its polypropylene copolymer resin shell is intended to resist impact, corrosion, solvents, UV exposure, and fungal growth. At 27.8 lb empty, this is a protective flight-style case for owners who need wheeled transport and a waterproof enclosure rather than a lightweight gig bag.
