Snubber
Definition and meaning of Snubber in real estate.
Snubber is a mechanical or spring-loaded hardware device installed on a door or window to control its closing speed and prevent slamming.
In more detail
In residential real estate, these hardware devices are most commonly seen on screen doors, storm doors, or heavy fire doors leading to garage spaces. They use mechanical tension, hydraulic fluid, or air pressure to slow down the door as it shuts, reducing wear on the frame and preventing injuries.
Home inspectors examine these devices for proper tension, ensuring doors close completely and latch securely without bouncing open. Homeowners can easily adjust the tension screw on the cylinder to alter the closing speed to fit their preference.

Frequently asked questions
How do you adjust the closing speed of a snubber?
Most snubbers have an adjustment screw at the end of the cylinder; turning it clockwise slows down the door, while counterclockwise speeds it up.
Why is my storm door slamming even though it has a snubber?
The snubber may need adjustment, or it may have lost its internal air pressure or hydraulic fluid, meaning the entire unit needs replacement.
