Red Glass Signal Dome with a Notched Flange
The red glass signal dome has a smooth curved body and a notched base flange.
Its open underside shows the mounting interface beneath the colored borosilicate dome.
For custom airfield signal designs, confirm color data, fit drawings and fixture testing before selection.
Use an approved physical sample and written color specification. Confirm the red color target and acceptance limits before ordering.
Specify the applicable standard edition and red color limits. Confirm measured coordinates and the required fixture level test evidence.
A circular base flange with visible notches surrounds the open underside. Match its dimensions and retention features to the fixture drawing.
The maximum diameter is 85 mm and the height is 60 mm. Confirm wall thickness, flange geometry and tolerances.
Agree on color coordinate limits, measurement conditions and batch inspection requirements appropriate to the intended signal light.
Confirm the complete mating geometry and optical requirements first. Similar external shapes alone do not establish interchangeability.
