The International Door Closer 883P 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 wether it is interior or exterior.  These days we usually use this door closer as a replacement of existing doors.   The closer features three adjustment valves for closing,latching speeds and one for back check.  The cylinder is constructed of precision cast aluminum.   It ships with a regular arm and parallel arm bracket.  This door closer is for use on doors up to 32” interior or 28” exterior doors.

Direct replacement for the older style Norton 1602 and 1603, and Yale 52 and 53
