The HamiltonBuhl Tripod also features a durable flame retardant and mildew resistant screen material, that can be cleaned with mild soap and water. Heavy-Duty, yet lightweight steel casing also features an ergonomic carry handle, for ease of transportation. The HamiltonBuhl Tripod projector screen also features a built-in keystone eliminator in the upper shaft, which allows the screen to tilt forward in multiple increments, in order to compensate for angled tabletop projection setups.
