Project like a Pro

Mounting your projector on the ceiling is one of the quickest and easiest ways to clear up clutter and create a polished, professional look in your home theater. There are many options when it comes to selecting a projector mount, and it can sometimes be difficult to determine which one you need. Crimson AV’s JR3 SyncPro universal projector mount eliminates much of the guesswork involved in purchasing a mount and even offers unparalleled flexibility during the mounting process. However, for larger projectors, the mounting hole pattern may not be large enough. When you need a wider footprint to go with your projector, the Crimson AV ADJR3 Adapter Extender is exactly what you need.

Universal Care

Attaching anything to the ceiling can seem like a challenge, but with the ADJR3 mount adapter, security and installation are never a concern. Crafted from aluminum and high-grade cold-rolled steel, this mount is rated for a projector weight of up to 70 lbs. The adapter extends the mounting pattern from 13.8” to up to 21.13” to accommodate larger and wider projectors. A sturdy, classic scratch-resistant epoxy powder coat helps protect the mount itself from unsightly scratches that might occur during installation or wear and tear.

The Crimson AV ADJR3 Adapter Extender attaches easily to the JR3 projector mount. Once installed, changes can be made as normal to the roll, pitch, and yaw of the projector mount itself.
