Fits Weber Smokey Mountain Cookers (14.5", 18.5", 22.5") with no drilling required. For other grills, adapt by drilling a 1.25" hole in the side to accept the probe. Measure temperature easily. The thermometer and probe port lets probes feed into the grill without crushing or damaging the sensor cord under the lid. The small round hole handles smaller probes, while the larger slot port accommodates large or dual probes. Durable and safe. Made from high-temperature resistant, food-grade silicone. Robust and built to last. Comparable to OEM parts, OEM part #85037. Easy to install. Quick and straightforward to fit, and supports multiple probes. Use scenarios: - Smoking on a Weber Smokey Mountain: monitor multiple meat temps plus grill temp without disturbing the lid seal. - Adapting a non-Weber grill: drill a 1.25" hole and route probes through the grommet for accurate readings. - Multi-probe or long cooks: use the small round hole for a single probe and the larger slot for a second or dual probes, keeping cords neatly under the lid.
