Weber Offset Concept

Introducing the Horizon WO500

I was listening to the podcast Shootin' the Que on BBQdb. Heath Riles and Matt Kusek were on the episode. Matt talked about how Weber has all types of grills: charcoal, gas, griddles, and pellet grills. My immediate thought was that Weber doesn't have an offset smoker. That gave me the idea to design a kettle-inspired offset for fun. I went down a rabbit hole of firebox proportions, airflow, and access around a big pit, and I used AI to help design it. Horizon WO500 is the result.

The concept pairs a 38-inch-diameter, 120-inch-long cook chamber with a 48-inch-long round firebox. Glossy black surfaces and rounded end caps carry the kettle influence across the chamber, firebox, and stack. The two cook doors, front shelf, and four-wheel frame give it the layout of a working offset.

The cook chamber

The cook chamber has two doors. Inside are two grate levels with removable panels. The six analog thermometers are arranged in pairs across the left, center, and right of the chamber, giving you a read at both cooking heights across the length of the pit.

Both ends have the same rounded kettle-inspired profile, and the glossy black finish continues over the chamber and the tall stack. The hardwood door grips and stainless front shelf break up the black. I wrapped a narrow red metal bar around the full shelf edge to tie the design to the red accents in Weber's newer design language. The shelf gives you room to set down trays and tools, then folds away for storage.

The firebox and airflow

The 48-inch-long firebox sits to the right of the cook chamber and connects directly through its rounded end. Its opening lid carries the same kettle-inspired curve as the chamber ends. I wanted the rotary air vent to mirror the familiar kettle-style vent. A vertical wood grip and one over-center latch centered on the handle complete the firebox door. A removable receiver holds cold ash for cleanup after the fire is out.

At the opposite end, the collector feeds a tall black stack with an adjustable damper. Four black-rimmed wheels support the black metal frame. The standoffs, top braces, and stack fittings are black as well. Leveling feet steady the pit when parked.
