HamiltonBuhl 80" Diag. (48x64) Portable Floor Rising Screen, Video Format, Matte White Fabric The HamiltonBuhl Floor Rising portable projection screen is the perfect companion for business presentations, trade shows, hospitality, a simple home theater or any portable application! Easily transportable and free-standing, the lightweight screen uses a manual telescoping pull up mechanism that lifts the screen from the casing. Once finished projecting, the screen retracts just as easily. The HamiltonBuhl Floor Rising projector screen comes with a built-in keystone eliminator, which allows the screen to tilt forward in multiple increments, in order to compensate for angled tabletop projection setups. The sleek black aluminum case features an ergonomic carrying handle and folding feet to add stability to the projector screen when it's open. A height adjustable bottom black border is also added to raise the screen further from the ground, to normal viewing height. The HamiltonBuhl Floor Rising screen also features a durable flame retardant and mildew resistant screen material with superior reflectivity and a matte white surface, rolled into a rugged and lightweight aluminum case.
