Rack guards help protect from oven burns. We’ve all been there: we reach into a hot oven to check on dinner when... OUCH! We accidentally brush up against that hot rack. These rack guards cover approximately 95% of the front rail of oven racks. They’re specially crafted from DuPont™ Nomex®... a material developed for firefighter uniforms to slow the transfer of heat to skin. Installation is easy, too—snaps onto the front rail of any standard oven rack. Oven-safe to 500°F. The fi re-resistant Oven Gloves can handle almost any hot surface… up to 400°F. Gloves provide full finger flexibility—great for use with the oven or grill, each fi ts both the left and right hands. Constructed of durable heat-resistant aramid and cotton. All are machine washable.
