Spring time weather challenges

Well, the weather is getting warmer and I think we can all appreciate that.  We at ESI would like to take this time to let people know that as the days get warmer their automatic door closers may work differently.  Most of these closers are hydraulic and as the air gets warmer the fluid will heat up, become thinner and thus allow a door to slam shut.  If this happens, please give us a call and we can adjust the door accordingly.
