The document discusses the history and types of sliding doors. It notes that sliding doors were used as early as the 1st century CE in Roman houses, as evidenced by archaeological finds in Pompeii, Italy. There are two standard types of mechanisms used to operate sliding doors - top hung and bottom rolling. In a top hung system, the door is hung from two trolley hangers at the top that run in a concealed track, taking all the weight, while bottom guides prevent sideways swinging. A bottom rolling system uses two rollers at the bottom running on a track with two top guides, with all the weight on the bottom wheels and more force needed to move the door.

8.  MOST OFTEN USED
 THE DOOR IS HUNG BY TWO TROLLEY HANGERS AT
THE TOP OF THE DOOR RUNNING IN A CONCEALED
TRACK
 ALL THE WEIGHT IS TAKEN BY THE HANGERS
 AT EACH END IS A TRACK STOPPER TO ABSORB ANY
IMPACT MADE IF THE DOOR IS SLAMMED AND TO
HOLD THE DOOR IN THE OPEN OR CLOSED POSITION.
 ALL TOP HUNG SLIDING DOOR GEAR SYSTEMS HAVE A
MAXIMUM WEIGHT LIMIT PAIR OF TROLLEY HANGERS
 AS THE DOOR IS HUNG AT THE TOP FROM TWO
POINTS,IT NEEDS ADDITIONAL GUIDES AT THE
BOTTOM TO PREVENT IT FROM SWINGING SIDEWAYS.

10.  SOMETIMES A TOP HUNG SYSTEM CANNOT BE
USED,AS THE WEIGHT OF THE DOOR CANNOT
BE SUPPORTED FROM ABOVE;IN THIS CASE
BOTTOM ROLLING SYSTEM IS RECOMMENDED
 IT CONSIS OF TWO ROLLERS AT THE BOTTOM
OF THE DOOR RUNNING ON A TRACK AND
TWO GUIDES AT THE TOP RUNNING IN A
GUIDE CHANNEL
 ALL THE WEIGHT IS CONCENTRATED ON THE
TWO BOTTOM WHEELS,MORE FORCE IS
NEEDED TO MOVE THE DOOR.
