Installation Manual 
•  A Side-by-Side Drive Thru, (See Figure 3) also known as a “Y” or 
“Merge” drive thru, is comprised of two lanes of ordering traffic side-
by-side, each with its own ordering point, but merges into a single lane 
with one or two drive thru windows for payment and pick up.

•  A Dual Drive Thru (see Figure 4) is comprised of two completely 
separate drive thru systems, each with its own lane, usually on opposite 
sides of the building, its own order point, and one or two drive thru 
windows for payment and pick up.  The simplest dual drive thru is two 
single drive thrus, but it is possible to have dual tandem, dual side-by-
side, or even a combination of different drive thru types.
