|Manufacturer||International Door Closer|
The International Door Closer 851P Series is not 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 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 32” interior or 28” exterior doors. The 851 meets the size 1 ADA requirements.
