Viking Standard and Quick Response Concealed Pendent Sprinkler VK4621 is a thermosensitive glass-bulb spray sprinkler designed for installation on concealed pipe systems where the appearance of a smooth ceiling is desired.
The addition of a reinforced nylon wrench allows for installation with the protective cap in place, minimizing the chance of damage to the sprinkler during installation. Viking also offers a cap removal tool to aid in finishing the job from the ground.
