Overview: This Chief RPM Elite (model RPMAU) is a locking universal ceiling mount for inverted front projectors. The
mount adjusts in all directions (pitch, roll, and yaw) to give you a perfectly shaped projected
picture. It has a quick connect/disconnect feature so you can conveniently
remove the projector to change the lamp and filter. The mount maintains its
angle, so you won't have to re-aim the projector when it is reattached.
Weight Capacity: The maximum
weight to be installed on the mount is 50 pounds. It is recommended that the ceiling's structural members can support a redundant weight factor five times the weight of the equipment you intend to install. If the structure cannot support that amount of weight, the structure must be reinforced before you install the ceiling mount.
Construction: All components of the RPMAU are made
of heavy-gauge steel for a secure and long-lasting mount.
Mounting Options: The RPM assembly can be mounted in variety
- Threaded Pipe: The RPM assembly has 1-1/2" diameter NPT threads to accommodate
mounting to an extension pipe.
- Wood Studs: The unit can be attached to wood stud
ceiling joists using four 1/4" x 3" lag bolts (not included).
- Concrete: The mount can be attached to concrete using
four Toggler A10 Alligator concrete anchors and four 1/4" x 3" lag bolts
- Threaded Rods: The RPM can be secured to uni-strut,
angle, or channel assembly overhead structural members (trusses or I-beams)
using 1/4" diameter threaded rods and 1/4-20 nuts (not included)
Main Parts: The RPMAU consists
of two main parts:
- RPM Assembly: Mounts to ceiling (see methods above) and
includes adjustments for pitch, roll, and yaw.
- SLMU Universal Interface:
Mounts to the bottom of the projector with the included legs and hardware.
The inverted projector, with interface attached, fits and locks into the
bottom of the RPM assembly.
Microzone Adjustments: The patent-pending Microzone
technology lets you make fine adjustments easily and quickly using a #2 Phillips screwdriver. The pitch adjustment
(setting the height of the projected image) is +/- 20°, the yaw adjustment
(setting the left/right position of the projected image) is also +/- 20°, while
the roll adjustment (leveling the projected image) is +/-3°
Note: The total yaw adjustment is 360° for some mounting
methods, but the setting can be finely adjusted +/- 20° once the projector
Centris Technology: The patent-pending Centris Technology
gives you effortless fingertip positioning of the projector. The mount
self-adjusts to support different projector weights.
Cable Management: The top of the RPMAU projector mount has a
1-1/2" diameter hole that allows you to easily route cables without additional
Q-Lock Quick Release Lever: You can easily remove and
reinstall the projector for quick maintenance. A simple lever holds the
projector to the mount, while the Q-Lock provides enhanced security with an
integrated key and lock system. When the projector is removed in this manner,
the mounting registration is maintained, preventing you from losing your preset
All-Points Security: The Chief RPMAU projector mount
utilizes All-Points Security with its exclusive steel-into-steel locking
hardware at all connection points to protect against theft. Using the supplied
security hex head screws, requiring the use of the supplied security hex
wrenches, secures the projector to the mount. Standard screws are also supplied
if you choose not to use the special security hex screws.
Supplied Hardware: The RPMAU can accommodate a variety of projector mounting patterns and screw sizes.
The mounting legs allows the SLMU plate to cover an area approximately 18"
in diameter. The RPMAU comes with M3, M4, M5, and M6 mounting hardware in short
(12mm) and long (25mm) lengths.
