The ESM-8 wildfire structure protection sprinkler kit is designed to help defend buildings from approaching wildfire by distributing water around structures and surrounding vegetation. It delivers rapid-deployment structure protection using eight patented Elevated Sprinkler Mounts (ESM) equipped with Rainbird Model 30H brass impact sprinklers. Designed to match the output of a Mark III or Wick 375 pump, this kit provides 360-degree coverage across a 100-foot diameter circle per sprinkler—equivalent to 0.8 inches of rain per hour at 50 psi. The system includes multiple mounting options: ground spikes for soil placement, direct attachment to poles or 2×4 lumber, and OTR (On The Roof) mounts for elevated positioning when ground installation isn't practical. All mounts feature steel construction with red powder coat finish and are manufactured in Canada by A.S. Roach Fire Services Ltd. Spray distance is dependent on water pressure at the source. Performance figures are based on optimal operating pressure — actual coverage will vary based on your pump/output source and supply line conditions.

The kit is designed to match the performance potential of a Mark 3 Q: How do I mount the sprinklers? Three options are included: ground spikes for soil installation, direct attachment to poles or 2×4 lumber, or OTR mounts for rooftop placement without nails. Q: What's the OTR mount for? The On The Roof mount is a free-standing unit for situations where a 16-foot pole on a ground spike isn't tall enough, or when ground conditions don't allow spike installation. Q: What are the sprinkler mounts made of? Steel construction with red powder coat finish and a vertical ¾" GHT female swivel water intake to prevent hose kinks. Q: What type of sprinkler heads are included? North American manufactured Rainbird Model 30H agricultural grade brass impact sprinklers with 360-degree rotation and two nozzles for even distribution. Q: What's the hose pressure rating? The included fire hose style flat-lay hoses are rated for 150 psi operational pressure. Q: How heavy is the kit? 77 lbs total. Carry box dimensions are 24" × 19½" × 12½".
