Brass sprinkler head extensions are used in a fire sprinkler system to extend fixed nipples (drops) that have been cut too short to place the sprinkler head at the proper working height — typically where mild variations in drop ceiling height cause sprinklers to sit too far into the ceiling. They are manufactured to fit both half (1/2) inch and three-quarter (3/4) inch sprinklers and are available in various lengths to allow for exact placement of the sprinkler head.
Brass sprinkler head extensions are a convenient and cost-effective way to reduce assembly time due to manufacturing or engineering errors or to retrofit existing systems. They provide good thread-to-thread contact at both the male and female connection. As is true whenever the original design of the system is altered, be sure to check with local authorities to obtain approval for any modification.

What if I need more length and flexibility than brass sprinkler head extensions offer?
In some installations, flexible sprinkler drops may be a good option for the precise placement of fire sprinklers. These flexible steel hoses come in up to 71″ lengths and are used for precise placement of sprinkler heads in environments with drop ceilings or in earthquake-prone settings requiring seismic design.
