Southbend “Ultimate” 60″ Restaurant Range

4 Star/Sauté Burners • 36″ Charbroiler (Left) • Standard + Convection Ovens • 305,000 BTU

Built for high-volume kitchens that refuse to compromise, the Southbend Ultimate 60" Range combines blistering top-end power with the versatility of both a convection and a standard oven base. Heavy-duty stainless construction, a factory-installed regulator, and simple battery-spark ignitions keep the line moving shift after shift.

Why You’ll Love It

  • Explosive top-side heat – four 33,000 BTU star/saute burners for even, edge-to-edge flame coverage.
  • True char-taste indoors – 36″ cast-iron charbroiler (left side) delivers 96,000 BTU for perfect grill marks.
  • Dual-oven flexibility – 45 K BTU standard oven for roasting & holding plus a 32 K BTU convection oven for fast, even baking.
  • Battery spark ignition on both ovens—no external power or standing pilot required for lighting.
  • Front-mounted gas shut-off lets staff secure the entire range instantly in an emergency.
  • All-stainless exterior (front, sides, shelf & 22.5″ flue riser) stands up to daily commercial abuse and wipes clean fast.
  • Four removable cast-iron grates handle pans up to 14″ and pull out for sink-side cleaning.
  • Factory-installed 3/4″ regulator, adjustable 6″ stainless legs, and CSA Flame, CSA Sanitation & NSF approvals included.

Important:
