6 Best Smoker Boxes for Gas Grills in 2026

If you’re looking for an affordable, yet high-quality smoker box, the Weber Stainless Steel SmoGas grills are fast, convenient, and easy to control, but they do not naturally produce the deep wood-smoke flavor associated with charcoal or offset smokers. A smoker box offers a simple solution. Fill it with wood chips, position it over a lit burner, and the vents release smoke around the food while helping keep the chips from igniting too quickly.

The best smoker box for a gas grill should fit beneath or on top of the cooking grate, withstand repeated high heat, and provide enough airflow for steady smoke. We compared current options by material, size, lid design, capacity, and grill compatibility. The six models below cover compact grills, large gas grills, heavy-duty use, and cooks who want more control over smoke output.

1. Kaluns Universal Stainless Steel Smoker Box – Best Overall

The Kaluns Universal Smoker Box balances compact size and useful capacity. It measures about 8.75 by 3.75 by 1.63 inches, holds roughly 6.35 ounces of wood chips, and fits many full-size and portable gas grills. Its vented stainless-steel body releases smoke while keeping ash contained.

The attached hinged lid simplifies refilling after the box has cooled enough to handle safely. Its low profile also makes below-grate placement possible when the grill provides sufficient clearance.

Pros:

• Compact enough for many grill layouts
• Holds about 6.35 ounces of wood chips
• Hinged lid provides convenient access
• Works with wood chips or pellets

Cons:

• Smaller capacity than extra-large boxes
• May need refilling during a long cook

Best For: Most gas-grill owners who want an affordable, compact, and easy-to-use smoker box.

2. Napoleon 67013 Stainless Steel Smoker Box – Best for Large Gas Grills

The Napoleon 67013 measures 16.25 inches long, 3.5 inches wide, and 2.54 inches high. Its extended stainless-steel body holds more wood chips or small chunks than a typical compact box and spreads smoke across a wider section of the grill.

The narrow profile can sit alongside a burner or below the cooking grid in a compatible full-size grill. Measure first, because its length may be unsuitable for portable and some two-burner models.

Pros:

• Long body offers generous wood capacity
• Narrow design works with many full-size gas grills
• Suitable for wood chips or small wood chunks

Cons:

• Too long for some compact grills
• Costs more than many basic smoker boxes

Best For: Full-size gas grills with enough room for a long, high-capacity smoker box.

3. Skyflame Wood Chip Smoker Box – Best V-Shaped Option

The Skyflame uses a double V-shaped base that can rest between the flame-deflector bars of many gas grills. This brings the wood close to the heat while keeping ash contained. The box is approximately 12 inches long, 3.3 inches wide, and 2.5 inches high.

Dense, wavy lid vents distribute smoke across the grill, and the hinged design provides access to the wood compartment. Its larger capacity suits ribs, chicken, and other longer cooks.

Pros:

• V-shaped base fits between many flame deflectors
• Large capacity for longer smoke production
• Dense lid vents spread smoke across the grill
• Works with gas and charcoal grills

Cons:

• Shape may not sit securely in every grill
• Requires more space than a compact rectangular box

Best For: Gas grills with flame-deflector bars and enough room for a larger box.

4. Kingsford Stainless Steel Smoker Box – Best Easy-to-Clean Pick

The Kingsford Stainless Steel Smoker Box is a practical choice for grill owners who want simple operation and easy cleanup. Its heavy-duty stainless-steel construction resists rust and helps reduce warping when exposed to the high temperatures of a gas or charcoal grill.

Measuring 9.05 by 3.74 by 1.57 inches, it has a narrow profile that fits beside food without occupying too much cooking space. The removable lid makes adding wood chips straightforward, while the dishwasher-safe construction simplifies cleaning after the box has completely cooled.

Pros:

• Heavy-duty stainless-steel construction
• Rust-resistant and durable
• Compact design fits many grills
• Removable lid provides easy access
• Dishwasher-safe construction
• Suitable for gas and charcoal grills

5. Broil King 60190 Premium Smoker Box – Best Smoke Control

The Broil King 60190 has two chambers and an integrated sliding air damper. The chambers can hold two chip varieties or chips in one section and a compatible flavorful liquid in the other. The damper adjusts airflow and smoke release.

Its hinged stainless-steel box can sit on the cooking grid or a Broil King Flav-R-Wave. It may also work with other grill layouts when the fit and placement are suitable.

Pros:

• Two chambers increase versatility
• Sliding damper helps regulate smoke output
• Hinged lid provides easy access
• Works with wood chips or pellets

Cons:

• More expensive than a basic smoker box
• Best fit is often on a Broil King grill

Best For: Grill owners who want adjustable airflow and more control over smoke intensity.

6. Grillaholics Smoker Box – Best Extra-Large Capacity

The Grillaholics box uses extra-thick stamped stainless steel and provides more capacity than many compact models. Its larger chamber is useful for extended cooks, and it accepts wood chips or pellets on gas or charcoal grills.

The hinged lid keeps wood and ash contained. Check the clearance between the burner covers and cooking grates before buying, because this extra-large model may crowd a portable grill.

Pros:

• Extra-large wood-chip chamber
• Thick stainless-steel construction
• Suitable for gas and charcoal grills
• Works with wood chips or pellets

Cons:

• May be too large for compact grills
• Larger capacity uses more wood per full load

Best For: Longer cooking sessions on full-size grills where frequent refilling would be inconvenient.

How to Choose the Best Smoker Box for a Gas Grill

Measure the available space: Check the gap between the burner covers and grate plus the open space above it. Compact boxes are easier to fit; long or V-shaped models offer more capacity on large grills.

Choose the material: Stainless steel is light and easy to maintain. Cast iron retains heat better but is heavier and must be dried carefully. Thicker metal is generally less likely to warp.

Check the lid and vents: A hinged lid simplifies access. More ventilation can create smoke quickly, while an adjustable damper provides better control. The lid should keep chips and ash contained.

Consider capacity: A small box suits burgers, vegetables, and short cooks; ribs and roasts benefit from a larger chamber. A smoker box adds flavor but does not turn a gas grill into a full-size smoker. For a stronger wood-fired profile, compare a pellet grill and a gas grill.

How to Use a Smoker Box on a Gas Grill

1. Make sure the smoker box fits securely without touching exposed fuel lines or blocking the grill’s airflow.
2. Add a modest layer of wood chips. Use dry or soaked chips according to the smoker-box manufacturer’s instructions.
3. Place the closed box over a lit burner, on the cooking grate, or below the grate if the grill and box are designed for that position.
4. Preheat with the grill lid closed until a light stream of smoke appears, then adjust the burner for the cooking temperature you need.
5. Cook over an unlit burner when possible and keep the lid closed.
6. After cooking, turn off the grill and let the box and ash cool completely before removal. Use heat-resistant grill gloves.

Avoid packing the box tightly or repeatedly opening the grill lid. Clean, thin smoke is preferable to a heavy cloud that can make food taste bitter.

Best Wood Chips for a Smoker Box

• Apple: Mild and slightly sweet; suitable for poultry, pork, and vegetables.
• Cherry: Mild and fruity; works well with chicken, pork, and ribs.
• Hickory: Stronger and savory; a classic choice for pork and beef.
• Pecan: Rich but usually milder than hickory; versatile for poultry and pork.
• Mesquite: Very strong; use it sparingly with beef or short cooks.

Avoid painted, treated, moldy, or resinous wood. Use wood chips sold specifically for cooking and smoking.

Frequently Asked Questions

Do smoker boxes work on gas grills?

Yes. A smoker box holds wood chips close to a gas burner so they smolder and release smoke around the food. The grill still uses propane or natural gas for heat; the wood supplies flavor rather than serving as the main fuel.

Should wood chips be soaked before using a smoker box?

It depends on the manufacturer’s directions. Dry chips usually begin smoking sooner, while some product instructions recommend soaked chips. Follow the directions supplied with the box and do not add flammable liquids.

Where should a smoker box be placed?

Place it over a lit burner, on the cooking grate, or beneath the grate above a heat shield if the grill and smoker-box instructions allow that position. Never block ventilation openings, fuel lines, or the grease-management system.

How long do wood chips smoke in a smoker box?

Smoke time varies with chip size, capacity, airflow, and burner setting. Compact boxes suit short cooks, while larger chambers are more convenient for ribs or roasts.

Can pellets be used in a smoker box?

Some boxes accept both chips and pellets; others are designed only for chips. Check the product instructions before changing fuel type.

Is a smoker box the same as a smoker?

No. A smoker box is a small grill accessory that adds wood-smoke flavor. A dedicated smoker provides more cooking space and better control for long, low-temperature barbecue. If ribs are a regular part of your menu, see our guide to the best BBQ smokers for ribs.
