What do those parts on a screen door closer actually do?
There's a little washer on the rod and a screw on the end of the cylinder. Most people who own one of these doors have never touched either.
Applies to
- Process
- Door hardware adjustment
- Materials
- Storm and screen doors with a tube-style pneumatic closer
- Setup
- A screwdriver, and about ninety seconds
- Two controls
- Hold-open washer on the rod · speed screw on the cylinder end
Why it matters
Carrying anything through a self-closing door is a two-hands-full problem with a one-hand solution that was fitted at the factory.
A closer set too fast slams, which eventually wrecks the frame. Set too slow, it never latches, and the door swings open in the first bit of wind.
What good looks like
- Push the washer up and the door stays open on its own
- Released, the door swings closed and latches without banging
- It latches every time, not most times
How to apply it
- Open the door and slide the washer along the rod up against the cylinder — the door now holds open.
- Pull the door to release the washer when you want it closing again.
- Turn the screw on the cylinder end to slow or speed the close.
- Adjust in small increments until it latches gently every time.
Exceptions & tradeoffs
Two-cylinder doors have a separate closer for the latching speed and the main swing. Adjust the right one, and check which is which before you start turning screws.
If it won't latch at any setting, that's usually a worn closer or a misaligned strike, not an adjustment problem.
Common mistakes
- Cranking the screw all the way in one direction to see what happensQuarter turns, then test. These have a small useful range
- Leaving it on hold-open in windThe washer holds the closer, not the hinges. Wind on a held-open door tears things
