Door Closer Information

The purpose of this page is to help you find a replacement door closer with the least amount of work to you.
The first step in choosing a replacement door closer is to measure your current door closers hole spacing, and
then find one on the chart below with the same hole spacing.  Does you closer have a sticker on it?  If so
at the bottom of this page we have some suggestions as to which manufacture you have.  And lastly, we have
some quick tips on how to adjust your door closer and a LCN Video on how they work.

Door Closer Adjustments

Tighten (clockwise) the valve to decrease the speed
Closing Speed Valve- The valve that controls the speed of closing from about 75 to 15 degrees,
some times marked "C" or "1"
Latching Speed Valve - The valve that controls the speed of the last 15 degrees,
some times marked "L" or "2"
Back Check Valve - The valve that controls the amount of resistance the closer has if it is
thrown open or if wind catches it.
Power Adjustment - This valve controls the spring tension, which will make the door closer open
harder or easier depending on were you adjust it. Only a few models have this option.
