Basically you turn the screw to the right to slow it down and turn it to the left to let it close faster.
Adjust tension norton door closer.
Bring a step ladder tall enough so that you can easily reach the door closer from the second or third highest step.
If there is just one screw on your door closer turn it clockwise to increase the speed with which the door closes.
Locate the tension adjustment screw at the end of the pneumatic cylinder.
After doing some research i found that most door closers have a few ways to adjust them including a swing how fast the main swing is and a latch how fast it closes at the end.
Counterclockwise to reduce this speed.
If you can t see adjustment screws chances are the closer has a cover.
Look at the end of the cylinder closest to the bracket with the door closed to see the adjustment screw.
Closers shall have two non critical valves to independently regulate sweep and latch speed.
Climb the ladder and examine the closer.
Clockwise gives the closer more closing power which also makes the door harder to open and turning the screw counter clockwise will give the door less closing strength and makes the door easier to open.
Usually the cover is plastic but it could also be metal.
Along the way there have been a variety of other innovations including the aluminum alloy body narrow style non handed closers adjustable backcheck speed adjustments and special application arms.
It is used to adjust the spring strength force to close the door.
Closers shall have adjustable backcheck.
Door closers consist of a pneumatic cylinder which controls the speed of the door and a bracket which holds the cylinder to the door.
Adjust the spring tension first once you have the door swinging more or less how you want it and fine tune using the other three screws.
In later years norton door controls refined the rack and pinion closer and the concept of a valve controlled backcheck for hydraulic closers.
Regular arm and top jamb closers shall have a non hold open shoe permitting 15 7 1 2 power adjustment.
You should also aim for a swing and latch speed that close and latch the door in about eight seconds.
Closers shall be sized for each door.
Closer fluid shall contain lubricity and anti oxidation agents.
