Yesterday I went to see my old friends at New England Door Closer (photos of the purpose of my trip to follow!), and they showed me this little beauty. Classic!
OK Closer Nation – what’s the purpose of this creative modification?
UPDATE: You guys are good! SO MANY of you guessed that it’s a place to add fluid to replace what was leaking out of the closer. They would fill the reservoir and it would last a while longer without needing to be refilled. I can’t help but wonder what happened to the fluid that leaked out though…with this level of creativity you’d think they’d have come up with a method of catching it and recycling it! Thank you to Ron Longley for keeping it in the Creative Closer Museum and to Neil Scully for being my Vanna White. 😀
