KRes Series Residential Sprinklers

Our Residential Lineup Just Got Stronger

KRes Series sprinklers are residential pendent and horizontal sidewall sprinklers with a fusible link operating element. The durable design provides additional protection against impact damage. The link does not extend beyond wrench boss, reducing risk of damage during installation.

The robust design allows the KRes to be shipped and installed without a protective cover. No need to return to the jobsite to remove, and no “forgotten” protectors.

Specifications

  • Pendent 165°F (74°C), 212°F (100°C).
  • Horizontal Sidewall 165°F (74°C).

KFR Intermediate Level Sprinklers

Unmatched Value

The Reliable Models KFR56 and KFR80 Intermediate Level Sprinklers include shields which protect the operating element from cold-soldering caused by sprinklers located at a higher elevation.

Wrench-able guards protect the sprinkler from damage in areas subject to impact damage. The link does not extend beyond wrench boss, reducing risk of damage during installation. Compact design and low profile are ideal for snug installations.

No protective covers are needed for shipping or installation, and no “forgotten” protectors are left after installation.
