This ingenious gate system can be customized to surround any size and shape hearth. It protects tots from heat and flames, as well as the hearths rough corners and edges. Five 24" interlocking sections adjust in 10 degree increments. The walk-through door opens in either direction with a convenient one-hand adult release. The standard gate is 29 1/2" high and fits hearths 6' wide by 2' deep. You can add either 8" or 24" sections for larger areas. A great solution for grills and wood burning stoves. Made of tubular steel with a non-toxic, heat-resistant finish. This gate can be used between rooms and for wide openings. This gate is the strongest when its sections are set on an angle or slight curve.
