Passing rigorous testing, the Pelican 1610 Large Case was designed for extreme protection during the transport and storage of your most valuable gear. Three levels of Pick N Pluck foam can be arranged to cradle your gear snugly, keeping your equipment secure and organized. With an open cell core and solid wall construction, this case is both incredibly strong and lightweight compared to cases with a solid core wall. An automatic pressure equalization valve and O-ring seal work together to deliver a watertight and dustproof case. By balancing the interior pressure, this case is always easy to open and uses double throw latches, which feature classic 'C' clamps to provide sufficient leverage with just a light pull. Moving the case is no problem thanks to the retractable extension handle and smooth polyurethane wheels with stainless steel bearings.
