Permanently lubricated steel ball bearings combined with nylon bushings and heavy-duty spring assembly offers smooth operation even in demanding applications. The case design allows for hanging from a ceiling or flush mounting to a wall, providing all the flexibility you need. The screen can be cleaned with mild soap and water and is flame retardant and mildew resistant.
