Many of Viking’s frame-style quick response recessed pendent and horizontal sidewall and residential recessed pendent and horizontal sidewall sprinklers are available as pre-packaged “cocoon” units. The “cocoon” is a plastic shell intended to protect the sprinklers from mechanical damage while also enabling ease of sprinkler installation. Sprinkler cocoon units are available with a Chrome or White Polyester finish. The cocoon sprinklers are offered with the same temperature ratings as the regular sprinklers.
