Constructed from heavy-gauge zinc-plated steel for durability and corrosion resistance. Equipped with a static-conductive grounding strip as a standard feature to enhance safety. Available with black or white neoprene gaskets; additional gasket materials are available upon request. Temperature Range: Neoprene rubber gaskets operate between -50°F to 180°F, with high-temperature options available upon request. Silicone is to 400°F. **NOTE - These are not specifications nor recommendations, but general guidelines to heat properties of gasket materials.
