How much weight can a drop ceiling projector mount bear?

In using a drop ceiling projector mount kit, the projector and mount, when attached to a ceiling joist, can typically support as much as 3 times the weight of the heaviest projector (20 pounds). The homeowner wishing to install a projector mount for his theater projector, will often be concerned about the weight a drop ceiling mount can bear. If a projector and its mount are attached correctly to the drop ceiling, the heaviest of theater projectors, along with its mount, can be attached securely to a drop ceiling, without likelihood of becoming detached.
