Chief CMA395 angled mount, black
In a converted attic or under a cathedral ceiling, the slope complicates the installation of a projector: a mount screwed directly into the ceiling would follow the roof’s incline, leaving the image skewed. This Chief angled mounting plate sits between the ceiling and the mount’s extension column. It pivots to compensate for the slope and brings the column back to vertical, so the projector stays level regardless of the ceiling’s incline.
A pivot that compensates for the ceiling slope
The mounting plate consists of two parts connected by a hinge. The first, a flat plate, attaches to the sloping ceiling; the second carries the threaded connector that accepts the column. Once the angle is set, a through-bolt and a self-locking nut (fitted with a nylon insert that prevents it from loosening over time) lock the position. The adjustment range runs from -5° to +95°, a total range of 100°: it accommodates anything from a nearly flat ceiling to a steep roof slope, and extends to a vertical surface when the column needs to extend from a wall or a very steep sloping ceiling. The few negative degrees allow correction for a ceiling that is slightly out of level in the opposite direction.
A connector with a 1.5-inch NPT thread
The connector accepts extension columns with a 1.5-inch NPT thread, the American tapered pipe thread standard that Chief uses across all its fixed and adjustable columns. A tapered thread tightens progressively as it is screwed in, creating a rigid connection without play. A set screw then prevents the column from rotating once it has been oriented toward the screen. The mounting plate is just one of the three components in the mounting assembly: it must be paired with an extension column of a length suited to the ceiling height, followed by a Chief projector mount, either universal or designed for a specific model, which screws onto the bottom of the column.
Three slotted holes for precise installation
The ceiling plate has three slotted holes rather than round holes. This detail allows some horizontal and vertical adjustment after drilling, useful for aligning the projector with the screen’s centerline without drilling again if the anchors or screws are not exactly where intended. The mounting plate is made of steel with a black finish and supports up to 227 kg, a figure far beyond the weight of a home projector. In practice, an installation’s limit depends on how securely the fasteners hold in the ceiling: the plate must be screwed into a structural member (rafter, purlin, concrete slab), not merely into plasterboard. With an overall length of 19 cm, a height of 11 cm and a width of 8.6 cm, the part remains unobtrusive at the mounting point.
Supplied hardware and installation preparation
The box contains the hinged mounting plate, the cathedral ceiling plate, the column connector assembly, the hinge bolt with its self-locking nut and two washers, the set screw, two machine screws and the hex key needed for tightening. Ceiling fasteners are not included: they must be chosen according to the mounting surface (wood screws for timber framing, suitable anchors for concrete). Before drilling, it is best to measure the exact slope angle and identify the lens position relative to the screen, as this point determines the mounting plate’s location and the required column length.

Frequently asked questions
Is the mounting plate enough to mount a projector?
No. It serves as an interface between the ceiling and an extension column with a 1.5-inch NPT thread. You need to add the column, then a projector mount that attaches underneath the device. Chief offers these three components separately or together as a kit.
What column length is needed under a sloping ceiling?
The length depends on the height of the mounting point and the position the lens needs to occupy relative to the screen, generally level with the top edge of the image for a projector mounted upside down. Under a sloping ceiling, the height of the mounting point varies depending on where the mounting plate is attached, so it is best to measure at the exact location chosen. An adjustable column allows a few centimetres of adjustment if the measurement is not perfect.
Does the plate allow you to adjust the image orientation?
It compensates for the slope in a single plane, that of the hinge, to bring the column back to vertical. The orientation towards the screen is adjusted by rotating the column before tightening the set screw, and fine adjustment (projector tilt, rotation, roll) is carried out at the projector mount.
Can it be used on a flat ceiling?
Yes, the adjustment range includes 0°, and the few negative degrees allow you to compensate for a slightly uneven ceiling. For a perfectly level ceiling, a fixed ceiling plate is sufficient and provides a more compact installation.
Can the mounting plate be attached to plasterboard?
Avoid attaching it solely to the plaster lining. The plate must be screwed into the roof framing (rafter, purlin) or a concrete slab, using fixings sized for the supporting material. If no structural element is in the right position, a crosspiece secured between two rafters above the ceiling provides a solid anchor point.
Is it compatible with floorstanding speakers from other brands?
It screws onto any tube or accessory with a 1.5-inch NPT thread. Push-fit or metric-threaded tubes, commonly used on other mounts, are not compatible.
Is there a white version?
Yes, Chief offers this plate in a white finish under model number CMA395W, with the same specifications and adjustment range. White blends in better on a light-colored ceiling, black in a dedicated room with dark walls.
