Crutchfield Customer Review (What's this?)
This is a very excellent mounting plate when used with CMS006009 extension rod and any Chief projector mount. After doing tons of research on projector mounts, this is the best combination on the consumer market period. The instructions are very detailed, mounting bolts are not supplied as there are many different configurations possible and it is up to you to determine best solution.
Pros: Solid construction Detailed instructions
