This is the W.A.S.P. Wildfire Protection Kit, it installs either on your ridge ends or clips directly onto your gutter. It will fit on either OG or Facia gutter styles. The kit comes with 2-25 foot industrial quality hoses, two sprinkler heads, two gutter mounts, and two ridge end clips. Basically, you can quickly clip these onto your ridge or gutter using a piece of 3/4″ PVC (not supplied), turn them on, and have your roof soaked to help prevent ignition during fires. Depending on water pressure, these can have up to a 34′ radius. 1.5 gallon per minute flow rate PER head.
