Operation
Retractable screen doors are also installed on reachable skylights, greenhouses, boats, houseboats and recreational vehicles.
The range of disappearing screen doors varies from inexpensive 'do-it-yourself' installed models; to high quality or custom made professionally installed models. Options are available, including: a variety of colors, wood grain finishes, pet or solar mesh, speed reducers, locks, and door bells.
Models made with built-in speed reducers greatly reduce the chance that fingers will get pinched as the screen retracts into its housing. Screen material made of nylon, known as "superscreen" or "pet mesh" provides a more durable, lower maintenance solution.

Famous quotes containing the word operation:
“Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.”
—Francis Bacon (1560–1626)
“It is critical vision alone which can mitigate the unimpeded operation of the automatic.”
—Marshall McLuhan (1911–1980)
“It requires a surgical operation to get a joke well into a Scotch understanding. The only idea of wit, or rather that inferior variety of the electric talent which prevails occasionally in the North, and which, under the name of “Wut,” is so infinitely distressing to people of good taste, is laughing immoderately at stated intervals.”
—Sydney Smith (1771–1845)
