This is the GREEN LIFE air outlet guard SZG-40. It is a silicone-type air outlet guard specifically for kerosene fan heaters. It can be installed on heaters with a minimum width of 27cm to a maximum of 56cm. The condition is used, so there is some discoloration due to heat. Also, I cleaned it because there was dust, but there are some areas that I couldn't completely remove. Please check the photos before purchasing. No accessories included. Shipping and handling fees apply, so significant price reductions are not possible.
