The International Door Closer 854P Series is a common closer we see on a lot of storefront aluminum framed doors.  This is one of the last closers out there to still have sizing.  By sizing I mean each door closer has a spring size of different tension so the closer is selected depending on door size and whether it is interior or exterior.  These days we usually use this door closer as a replacement of existing doors.   The closer features two adjustment valves for closing and latching speeds.  The cylinder is constructed of precision cast aluminum.  If you have an exterior door I would recommend the 880 Series, which is the same door closer, but has a back check valve.  The back check valves will slow the door down if it is caught by a gust of wind.  It ships with a regular arm and parallel arm bracket.  This door closer is for use on doors up to 42” interior or 36” exterior doors.
