The standard Gullsweep has been modified to suit this particular
application. The Gullsweep is ideal for the job, however the
top mounted location on such a screen porch framework does

the drive position. Utilizing a unique counter spring noise
suppresser as well as a sound insulator on the mounting base,
eliminates or substantially reduces an audible noise.
