Alpha OH600 Flush Mounting Box, Galvanized Steel

Built for reliable, professional installations, the Alpha Communications OH600 flush mounting box delivers a tamper-resistant, attractive enclosure for intercom housings used in security and surveillance systems. As a galvanized steel backbox, the OH600 protects sensitive entry panels and remote intercom stations from corrosion and physical damage while keeping wiring and electronics concealed. With a compact 2" depth, 4.3" width and 10.3" height, it fits common flush-mount lobby panels and can be set into concrete or attached to studs for versatile deployment.

Installers benefit from standard top and bottom electrical knockouts and adjustable tinnerman clips that allow the finished panel to be leveled even if the back box is slightly off—saving time on-site and reducing callbacks. The OH600 is ideal for access control, monitoring, video intercom and general security applications where durability and neat integration matter. Backed by a 1-year limited warranty, this Alpha Communications intercom housing is a practical choice for commercial and multi-tenant installations. Order the OH600 to streamline your next intercom, entry panel or surveillance mounting project.
