St. Barnabas, Montgomery, has a Da-Lite Da-Mat front projection screen that is free to a good diocesan church home. It cost over $1,000 several years ago, but the church is no longer using it and will give it away if the recipient picks it up. It is heavy. It is very large when assembled, over 13′ tall with a screen size of 10′ 6″ by 14′ wide. It comes with a screen bag, heavy duty roller carrying case and all the legs and crank attachment parts.
Here is a link to a similar product: http://www.projectionscreensonline.com/da-lite-fast-fold-deluxe-106×14-complete-kit-da-mat-surface/. The church is unsure of the exact model number of their screen, but the screen size is 10′ 6″ by 14′, it is only front projection, and has T legs vs. the large triangle support option shown in the link. The legs are silver, not black, and there is a video in the link to show how to assemble.
Interested parties should contact the church at 513.984.8401.
