LAMAR SERVING LINE

> the total opening is 277 ½ inches. The first section is approximately 51 inches, and then there is a square steel pole from floor to ceiling that is 5 inches wide. The next section after the first pole is approximately 120 inches, then a 5 inch pole again the last section is approximately 96 inches. The poles are structure and cannot move. There is a drop down from the serving line floor to the kitchen floor

>

> Section 1 51"

> Section 2 120"

> Section 3 96"

> Starting from section one traveling to the end of section 3 we would like a hot/cold well followed by 5 hot wells, then a 3ft frost top cooling section, then a built in ice cream freezer, and ending with a point of sale station.

> We have 208v 50 amps available for service to this unit. Field measurement required before start of project.
