RKI has upgraded the seals and increased the size of what the maker claims to be the industry's largest-capacity truck boxes. Automotive-style, ribbed D-bulb seals resist water, dust, dirt and other contaminants. Closed-cell EPDM seal material resists taking a compression set; aging; UV, ozone and oxidation; and can withstand temperatures above 300°F.
