Screen Doors and Speed Reducers
Most houses these days are have at least one retractable screen door. More often than not these can be found in the back of the house leading to a pool, patio or yard. It is rather pleasant to leave the door open on nice days without letting a swarm of bugs into the house. This is where the retractable screen door comes into play. However there always seems to be one fly who manages to sneak through the wire mesh defenses and drive the inhabitants inside incredibly insane.
Although screen doors serve as the front line against pesky bug infestation they don’t come without drawbacks. I know more than one person (not including myself) that has attempted to run inside the house only to be thwarted by the screen door. If the sun hits it at just the right angle it can look almost invisible; at least to someone who isn’t paying much attention.
Retractable screen doors can easily get bumped off the tracks. This happens all the time to the screen door at my family’s cabin. We usually have to drag the screen door closed. Someone always buckles and puts it back on the track but it never stays there. It bumps off most likely because of the constant slamming of the screen door. There is a heavier glass door that must be opened before we open the screen door. Sometimes we forget and use the same amount of force to open the much lighter door tearing it away.
Some people install a speed reducer in their retractable screen door system to slow down the door right before it shuts. Supposedly people get their fingers pinched in the door and this can help prevent that as well. I’ve never had that problem but the speed reducer may help keep the door at our cabin on track. If the door slows down right before it shuts maybe it won’t jump out of its track. One can only hope.
