 For rear mount installation that are
limited on space for the gate to slide back
into, the space saver version is an excellent
alternative. There may be a property wall,
parking stall or other obstacle that reduces
the amount of space available, making it
difficult to mount the gate operator and still
have room for the gate to slide. The space
saver version of the gate operator places the
drive shaft externally so that the gate can
slide past the gate operator, picking up allot
of extra space. The external drive shaft can
be specified to be placed on either side of the
operator for left or right side installations or
can be easily converted in the field.
 Installation of the space saver version
is very much like the rear mount installation
of the standard gate operator. The chain
makes a continuous loop going around the
drive sprocket on the operator and around the
idler sprocket on the post or wall. For the
case of the space saver, the external drive
sprocket allows the gate to slide past the
operator, making installation possible where
there is only 4 inches of space left over after
the gate is open (see illustration at left).
