Heavy Duty Offset BBQ Smoker for Wood and Charcoal

This is the big one. The Colossus is a 24 x 48-inch offset smoker with over 2,000 square inches of cooking surface, built for competition teams, caterers, and restaurants that smoke by the case. A fire burns in the side firebox, and heat and smoke travel the length of the chamber before leaving through the stack. Fully welded 3/16-inch steel. Built in the USA.


Colossus Offset Smoker Features

  • 24 x 48-inch cooking chamber. A 24 x 48-inch main grate, a 10 x 43-inch top warming rack, a 14 1/2 x 10-inch warming plate over the firebox, and a grate in the firebox for direct grilling. Over 2,000 square inches in all.
  • Tuning plates included. Steel plates under the grate spread heat evenly from the firebox end to the stack end and kill hot spots.
  • Lid counterweight. The heavy lid opens with two fingers and stays put.
  • Two temperature gauges. One at each end of the chamber so you can see the gradient without opening the lid.
  • Offset firebox with dual dampers. Two intake dampers plus a 4 1/2-inch smokestack damper give you fine control over airflow, temperature, and smoke.
  • Side firebox door. Load logs and clean out ash from the end without opening the cooking chamber.
  • Probe port. Run your meat probe through the wall and leave the lid closed.
  • Fully welded 3/16-inch steel. Thick walls, heavy hinged lid, galvanized stay-cool handles. Rust-inhibiting primer under high-temp paint rated to 1200°F.
  • Grease drain and cup. Drippings run to a drain and hook-on cup.
  • Cart with storage. Heavy-duty frame, 35 x 18-inch wood storage shelf, detachable 38 x 13-inch front work shelf, and wheels on 1-inch axle bolts.
  • Included: 3/8-inch round bar cooking grate, warming rack, expanded-metal log/charcoal grate, tuning plates, two thermometers, fire poker, smokestack with damper, grease cup.

How to Use an Offset Smoker

Step 1. Build the fire. Light two chimneys of lump charcoal in the firebox, then add splits of oak, hickory, or pecan.

Step 2. Dial in the heat. Open the firebox dampers and stack wide to come up to temperature, then close down to settle at 225 to 275°F.

Step 3. Load and leave it. Meat goes on the main grate, probe through the port, lid closed. Add a split every 45 minutes or so.

Step 4. Clean up. Empty the grease cup, open the firebox door, and shovel out the cold ash.


What to Cook on an Offset Smoker

  • Smoke: Four briskets, a dozen racks of ribs, several pork butts at once. 225 to 275°F, hours at a time.
  • Grill: Burgers, sausage, chicken thighs on the firebox grate over direct coals.
  • Hold: Finished meat on the top rack, sides on the warming plate.

Which Size?

The Colossus is the 24-inch chamber. For backyard volume, see the 20-inch Yosemite or the 18-inch Denali.


Offset Smoker FAQ

Is it commercial grade? Yes. 3/16-inch welded steel and 2,000-plus square inches is restaurant and competition territory.

Will it rust? It's primed and painted carbon steel. Keep it covered and touch up chips with high-temp paint.

What do I burn? Split hardwood, lump charcoal, or both. Most people start with charcoal and feed wood.

How long until it ships? Made to order in the USA. Plan on about 4 to 6 weeks, plus shipping. It ships freight on a pallet; have a few friends and a flat path ready.
