JL Industries Crownline Stainless Steel Surface Mount Fire Department Valve Cabinet 8439S21

The JL Industries Crownline 8439S21 is a surface-mounted stainless steel cabinet for a single fire department valve on a standpipe system, made in the USA. The #4 brushed stainless construction suits premium lobbies, health-care, and food-service interiors where finish and cleanability matter. It bolts to the wall face with no wall cavity required, making it the right choice for stairwells, masonry walls, and retrofit locations. The solid stainless door has a pull handle, roller catch, and a continuous hinge that opens 180 degrees.
