This free-standing heater guard is the perfect way to safeguard children and pets from the heat of portable gas heaters and accidental injury. Compatible with most sizes of portable gas heaters. Please Note: This guard will get hot. Intended design: The purpose of a guard is not to stay cold, but to create a safer surface that prevents direct contact with the much hotter elements of the heater. A quick, accidental touch is less likely to cause a serious burn than touching the heater itself.
