The combination of a charcoal firebox with heat deflectors and a vertical rib-hanging smoker attachment creates a powerful low-and-slow cooking setup for your Weber 22-inch kettle.

One accessory focuses on what happens below the food—heat management and fuel efficiency. The other focuses on what happens above the fire—cooking capacity and airflow.

Together, they can turn your kettle into a more controlled and spacious smoker for ribs, chicken, brisket, pork and more.

How Does This Combination Work?

The two accessories serve different purposes, which is exactly why they complement each other.

The charcoal firebox sits inside the kettle and helps create a more concentrated and controlled charcoal-burning area. Its stainless steel structure, removable heat deflectors and ceramic heat stone are designed to improve heat retention, airflow and indirect cooking.

The vertical smoking attachment sits on top of the 22-inch kettle. It adds vertical cooking space and includes a three-tier hanging system with 24 hooks, allowing you to hang ribs, chicken, wings and other foods vertically instead of laying everything flat on a grate.

1. Better Heat Stability for Low-and-Slow Cooking

One of the biggest challenges when smoking on a kettle grill is maintaining a stable temperature for several hours.

Traditional charcoal setups can lose heat relatively quickly, requiring you to adjust the vents or add more fuel during a long cook.

The firebox addresses this by creating a more concentrated charcoal area and incorporating heat-retaining components. The ceramic structure is designed to hold and redistribute heat, while the removable heat deflectors help concentrate the heat around the charcoal area.

When paired with the vertical smoker attachment, this creates a more controlled environment for low-and-slow cooking.

Why it matters:

• More consistent cooking temperatures
• Better heat retention
• Less frequent charcoal management
• More controlled indirect cooking
• Better suited for longer smoking sessions

For cooks such as brisket, ribs and pulled pork, stable heat can make the entire process easier to manage.

2. More Cooking Capacity Without Buying a Bigger Smoker

A major advantage of the vertical smoker attachment is that it uses vertical space instead of simply expanding horizontally.

The attachment features a three-tier rib hanger with 24 hooks, giving you plenty of hanging positions for ribs, chicken, wings and other cuts of meat.

Instead of placing several racks of ribs flat on a cooking grate, you can hang them vertically.

This creates a different style of cooking environment:

Traditional setup:

Charcoal → Cooking Grate → Food → Lid

Vertical smoking setup:

Charcoal → Heat Management → Vertical Hanging Space → Food → Smoke Circulation

The result is a taller cooking chamber that can make better use of the space inside a 22-inch kettle.

3. Ideal for Ribs, Chicken and Other Hanging Foods

Hanging meat is one of the biggest reasons to add a vertical smoker attachment.

Ribs, chicken wings, drumsticks and other foods can be suspended from hooks instead of occupying the entire cooking grate.

This is especially useful when you're preparing food for a larger gathering.

For example, you can hang multiple racks of ribs vertically while allowing smoke and heat to circulate around the meat.

The openable front door also provides easier access when you need to check food or manage charcoal and wood during the cook.

4. A More Efficient Use of Your Weber Kettle

The biggest benefit of this combination may not be a single feature—it is the way the two accessories change how you use the kettle.

Instead of using your Weber kettle primarily for burgers, steaks and basic charcoal grilling, you can create a dedicated low-and-slow cooking configuration.

The firebox focuses on the fuel and heat source, while the smoker attachment focuses on the cooking chamber and food capacity.

That gives your kettle multiple cooking personalities:

Grill → Roast → Smoke → Hang → Low & Slow

You don't need to purchase a completely separate large smoker to experiment with vertical smoking.

5. Better Fuel Management for Long Cooks

Long smoking sessions require a reliable fuel strategy.

The charcoal firebox is designed with a larger fuel capacity than traditional small charcoal holders, allowing you to load more charcoal and wood. Its heat-retaining construction also helps reduce heat loss during extended cook
