ProEnc have now added to their portfolio to include stacking projector enclosures, due to a major project that needed the protective housings to be stacked.
The secure, protective housing was to accommodate high end Barco digital projectors ranging in cost from $20K to $60K! This is why ProEnc's solution was the prefered solution.
For more information, you can check out the information at goo.gl/BQpJpK. Something you will not regret, as ProEnc hosuings are often used to replace the competitions units that have failed in the field.
