The Pelican 1650 Large Case gives you superior protection and control. Built for durability even in extreme conditions, this case is dustproof, crushproof and watertight with a secure O-ring seal. The open cell core with solid wall design provides incredible strength while reducing weight, and an automatic pressure equalization valve maintains the interior pressure and fully blocks out moisture. The double throw latches use a 'C' clamp design that works like a pry bar for lots of leverage with just a light pull. To keep your valuables protected during transportation or storage, this case comes with two levels of Pick N Pluck with convoluted lid foam, which securely cradles your gear. A retractable extension handle pairs with four, sleek polyurethane wheels for a smooth ride. For secure, convenient storage and transportation, Pelican has you covered.
