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 — 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.

What fits
