The color of a sprinkler head rated 135° to 170°F is which color?

Explanation:
Sprinkler heads use color (or the absence of color) to signal their temperature rating, so inspectors can quickly verify that a head matches the system’s protection requirements. For the 135°F to 170°F range, many manufacturers designate the head as uncolored (clear) or black. That pairing—uncolored or black—indicates this lower temperature band, which is why it’s the correct choice. Other colors are used for different ratings, so they wouldn’t indicate the 135–170°F range.
