Sprinkler guard / cage

thingiverse

This is a guard to protect against accidental discharge of exposed fire sprinklers. As you may know, these sprinklers are usually activated by a small glass capsule that holds the valve shut -- if the capsule is bumped, you and your house are getting wet. This cage may provide some protection from accidental bumps, for example by someone carrying a tall object in a garage or shop. This is set up for a 3" diameter cutout, and is 2" high. 15% support necessary.
