Set of 2 oven rack guards fit easily over the exposed sides of your oven rack and protect your arms and fingers from inadvertent burns from the rack itself. Heavy duty snaps hold the guards in place and are completely covered with fabric so they won't heat up. Made from NOMEX, a fire retardant fabric used by fire fighters and race car drivers, they are safe for temperatures up to 500 degrees. Measure 18 x 3 inches when fully opened. Machine washable.
