Techniice Signature Series Ice Chest 25 YEAR WARRANTY. These Signature Series cool boxes are built with recessed Twin padlock facility for added security. The bung is a huge 2 inches diameter (about the size of a tow ball). This allows the box to be emptied quickly when leaving a camp site especially as there could be still many large chunks of ice left after weeks of camping that can be emptied through this bung. This box incorporates a fully moulded and integrated hinge system designed to last for a life time even in commercial applications. Dual Air Lock Seal System comprises one EVAS Seal plus a Rubber Fridge Gasket Seal. This system provides a perfect seal at virtually all ambient temperatures. 4 sturdy feet are provided that allow 360 degree air circulation that provides a cool thermal air barrier under and around the box so the box can be put on hot metal ute trays, trailers or hot ground surfaces without effecting the performance of the box through rising heat under the box. Dual Rope Handles, Heavy duty reinforced nylon handles with comfortable hand grips plus comfortable recessed carry ledge handles in the top body of the box lets you choose between the 2 options. Tie down points are provided via the rope handles or the integrated points on the base of the box. These Iceboxes have an Integrated ruler on the top of the lid that helps you measure your catch.
