Pole for poster support attachment and removal |
摘要 |
An elongated poster support arrangement comprising an elongated extrusion having an uppermost wall and a tapered sidewall which extends angularly from the uppermost wall. A central support wall is arranged between the tapered sidewall to define an elongated longitudinally disposed chamber between the tapered sidewall and the central support wall. The longitudinal chamber has a slot which is arranged to receive a lift tool to permit the poster support to be lifted to and removed from a ceiling rail. The tapered sidewall has a distal edge flange arranged to facilitate sliding engagement of a blade of the lift tool. The blade of the lift tool has a tapered lock member thereon for wedging between the flange and the support wall.
