How we specify in Houston
Houston rooms set the constraint. New builds in the Heights and Bellaire often hide the screen in a soffit or a motorized drop, while Memorial and River Oaks remodels usually keep a fixed frame wall and a dedicated rack. We measure ceiling height, throw distance and seating position before naming a model. For the Arc Ultra specifically, we confirm the fit against your room in Houston, TX before quoting the install.
Service area: Houston, Bellaire, Memorial, River Oaks, The Heights, West University Place, Sugar Land, Spring Branch.
