ABSTRACT:
A birdshield for closing off the back end of a luminaire having a slipfitter accommodating a range of pipe sizes, is formed from a substantially flat piece of moderately stiff and resilient material cut to a pattern fitting into the rear of the luminaire. A hole through the piece accommodates the smallest size of pipe and a lune-shaped knock-out may be torn out for larger sizes. Bent-out tabs on each side engage the upturned end wall of the slipfitter yoke to hold the birdshield captive.
