be stored upon the deck 18 when not in use as shown in fig2 and 5 when the telescoping bleachers 12 are to be used they are pulled out from a wall of a gymnasium and fully extended the end rails 14 one on each end of a row of seating are removed from the deck 18 of the bleacher 12 the two rail sections 62 and 64 of the end rail 14 are unfolded and the stub shafts 80 and 106 are inserted into the first and second socket 30 and 32 once the end rail 14 is positioned in the first and second socket 30 and 32 thumb screws 44 and 56 are tightened to secure the end rail 14 to prevent removal of the end rail 14 from the base plate 16 the end rails 14 for each row of seating is installed in the same fashion until every row is completed when the event is over and the bleacher 12 is to be stored the end rails 14 can be removed by loosening the thumb screws 44 and 56 and removing the end rails 14 from their respective base plate 16 the end rails 14 are then folded in half and stored upon the deck portion 24 of the bleacher 12 the benefit of the end rail 14 design is their light weight allowing a single individual to set up the bleachers without the assistance of others also if the entire bleacher 12 does not need to be used it can be opened part way and the end rails 14 can be installed only for.
