There are many different types of manual projection screens.  The one thing all manual projection screens have in common is that they must be raised and lowered by a person verses an automatic, motorized system.  Manual projection screens are much less expensive than the motorized counterparts.

A manual screen can be fixed or portable.  Fixed manual screens usually have a casing at the top where the screen is stored when it is rolled up and some sort of weight at the bottom, most often a strip of wood, that helps the screen stay open and flat.

The fixed screens are usually mounted on a wall and are meant to stay in the same place.  Portable screens are made the same way, but instead of being fixed to a wall they are set up on a tripod.  These screens can be taken from place to place as needed.

Manual projection screens work much like a flat blind.  They are held in place until a person chooses to release them.  Some have a hook at the bottom to ensure the screen does not roll up unintentionally.  When it is time to store the screen the person tugs lightly on the bottom and the screen rolls up into the casing.

Manual projection screens are often used in environments where the screen is going to be used often, but space is a concern.  These screen are easily stored and easy to use.  Manual projection screens work great for a person on a budget, too. They come in various materials and are very comparable to the more expensive motorized screens.
