The Alpha Communications®/Tektone OH300 series surface housings are used exclusively with the OF200 series lobby panel and annunciator frames.

All OH300 series surface housings are 17.75" high (429mm) and project off of the surface of the wall 3.63" (93mm). The last digit of the model number indicates how many modules in width the housing can accomodate. For example, a model OH303 can handle '3' modules in width, and will require the OF203 matching frame. All OH300 series surface housings are made of heavy-duty steel, in a Black painted finish. The OH300 series housings are made a maximum of 8 modules wide (model OH308). For larger applications, we recommend that you use several housings, with several frames.

For flush mount applications, use the OH200 series flush mount housings with the OF200 seriesframes.
