ABSTRACT:
A ceiling access panel for a suspended ceiling has a friction brake to retard the pivotal movement of the panel from a raised condition flush with the ceiling to a lowered condition exposing a ceiling access opening. The friction brake comprises a flexible band having a first end anchored to the access panel, a second end fast to a bracket upstanding from the access panel, and an intermediate portion passing around and between a pair of rollers mounted on an access frame portion of the ceiling structure so that when the weight of the access panel is applied to the first end of the band, the band is drawn onto itself, frictionally to resist further lowering of the access panel.
