Roto-Rugged Cases are manufactured by rotational molded dense polyethy lene. This special process assures thick, impact resistant corners and provides uniform wall thickness for strength and durability. The special luggage cart capability is built-in and is designed to provide stability and easy transport. A telescoping handle extends to a comfortable 40" length for balance while heavy-duty, full ball bearing wheels allow ease and mobility. But the features don't stop there. This professional case includes features like: baked on black powdered coated finish that resists scratches; hand fitted tongue and groove aluminum valances: cable lid stays to prevent the lid from accidentally closing on you; heavy-duty, full length piano-hinges; comfort steel-core padded leather handle and recessed military style latches with padlock loops for lock. The Roto-Rugged Tote-Wheeled Case is designed to accept a weight of 250 pounds-per-square inch. (USA) Inside Dimensions: 25"L x 22"W x 18"H; Lid/Bottom: 3 + 15; Weight: 35 lbs.; Color: Charcoal.
