Recessed sprinklers are a type of fire sprinkler system that is designed to be installed into a ceiling or wall cavity, resulting in a flush-mounted appearance. These sprinklers are commonly used in commercial and residential buildings to provide fire protection by automatically spraying water onto a fire in its early stages, helping to contain the fire and prevent it from spreading.

Flexible sprinkler droppers are an innovative and flexible solution for fire sprinkler systems. They consist of a flexible hose that connects the sprinkler head to the branch line, allowing for greater flexibility in the placement and positioning of the sprinkler head.
