It stands just 16.5\" tall with an offset lid, holds 8.85ft³, and locks with dual Secure Lock twist handles that sit nearly flush in the front panel. The tub is a single piece of 0.058\" aluminum, the lid is UWS's patented RigidCore foam-filled design so it will not flex or bind, and a MicroSeal gasket runs the full perimeter of the opening to keep rain and dust out. The finish is matte black powder coat over diamond plate. This is the heavy-packaging version of the box: mechanically identical to the standard part, but crated for parcel carriage so it can ship without freight. UWS designs, fabricates and welds it in Florida and backs it with a limited lifetime warranty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUWS 48\" Under Tonneau Chest Box in Matte Black, part EC20503\u003c\/li\u003e\n\u003cli\u003e2 keys\u003c\/li\u003e\n\u003cli\u003eMounting hardware kit, on the models that include one (see the note below)\u003c\/li\u003e\n\u003cli\u003eMAY NOT BE INCLUDED: UWS states that not all chest box models ship with the mounting hardware kit, and does not say which.

On a wide bed that is the difference between grabbing a tool and climbing up into the bed to get it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePatented RigidCore Foam-Filled Lid\u003c\/strong\u003e\u003cbr\u003eUWS fills the lid with a solid foam core instead of leaving it hollow. That is what stops a long lid from flexing in the middle, binding in its own opening or drumming as you drive. On a 48\" lid this is the difference between a box that still latches cleanly after a few years and one that has to be pushed down to catch.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLimited Lifetime Warranty\u003c\/strong\u003e\u003cbr\u003eUWS backs the box with a limited lifetime warranty, with one year on the finish and one year on parts.

Loose cargo cannot fall against it and bend it, which is the usual reason a two-handle box eventually stops opening from one side.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual-Locking Secure Lock Handles\u003c\/strong\u003e\u003cbr\u003eSecure Lock twist handles lock on both sides of the box and are joined by a connecting rod, so it opens from either side and locks from either side. They sit almost flush in the front panel, which is what lets the box live under a tonneau cover without fouling it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExtra-Thick 0.058\" One-Piece Aluminum Tub\u003c\/strong\u003e\u003cbr\u003eThe tub is formed from a single piece of 0.058\" aluminum rather than welded up from thinner panels, so there are fewer seams to leak or split and the box keeps its shape when it is loaded with heavy hand tools, cordless kits and chain. Aluminum also means it will not rust out from the inside the way a painted steel box does once the coating is chipped, which matters on a box that lives outdoors and gets road salt thrown at it every winter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesigned, Fabricated and Welded in Florida\u003c\/strong\u003e\u003cbr\u003eUWS designs, fabricates and welds its tool boxes at its own plant in Florida. That is unusual at this price and it shows up in the things that are hard to fix later: consistent weld quality, lids that sit square, and gaskets that actually meet all the way round.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSelf-Opening Lid\u003c\/strong\u003e\u003cbr\u003eRelease the Secure Lock handles and the lid lifts and stays up on its own, close to a full 90 degrees.

It is now part of the Lippert and CURT Group family, which is what gives a box at this price a real dealer network, real parts support and a warranty that means something years later. What has not changed is where the boxes are made: UWS designs, fabricates and welds them at its own plant rather than importing finished bodies, and that is visible in the details that cannot be fixed after the fact, such as square lids, consistent welds and gaskets that meet cleanly all the way around the opening.\u003c\/p\u003e\n\u003cp\u003eTwo UWS features do most of the work in this under tonneau chest box. The first is the patented RigidCore lid, filled with a solid foam core instead of left hollow, which is what stops a long lid flexing in the middle, drumming at speed or binding in its own opening as the box ages. The second is MicroSeal, a full-perimeter gasket that compresses as the lid closes and keeps out the rain, road spray and fine grit that ruin the contents of a cheaper box. Underneath both is a 0.058\" one-piece aluminum tub, thicker than most of the competition and immune to the rust that eventually kills a painted steel box.\u003c\/p\u003e\n\u003cp\u003ePrestige Truck is an authorized UWS dealer. Every box we ship is new, factory-packed, covered by the full UWS limited lifetime warranty and supported by UWS's US-based parts and service team.\u003c\/p\u003e","brand":"UWS","offers":[{"title":"Default Title","offer_id":48935882555636,"sku":"UWSEC20503","price":830.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/4784\/0244\/files\/uws-ec20503-48-in-under-tonneau-chest-box-matte-black-studio-a.webp?v=1785304062","url":"https:\/\/prestigetruck.com\/products\/uws-48-in-secure-lock-under-tonneau-chest-box-matte-black-ec20503","provider":"Prestige Truck","version":"1.0","type":"link"}
