This replacement set of grill caster wheels is designed to fit a wide range of popular gas grills, specifically compatible with Charbroil Performance caster sockets, G408-0036-W1, 463243518, 463342119, Thermos 461246804, and Kenmore 415.16123801 models. Each wheel is constructed from durable, high-temperature nylon that resists cracking and deformation under prolonged heat exposure near the grill base. The smooth-rolling caster design allows effortless movement across patio or deck surfaces, while three of the four wheels feature a locking mechanism that securely keeps the grill in place during cooking or when positioned on a sloped area.

The mounting stem is precision-machined to fit standard 3/8-inch caster sockets, ensuring a stable and wobble-free installation. Each wheel is reinforced with a corrosion-resistant zinc-plated bracket that withstands outdoor moisture and routine cleaning without rusting. The rubber tread provides excellent traction on concrete, tile, and wood surfaces, reducing the risk of the grill sliding during use.

The 1.75-inch wheel diameter balances maneuverability with sufficient clearance for uneven ground, and the total load capacity supports most full-size gas grills without sagging. Replacing worn or broken casters with this four-pack restores the original mobility and stability of the grill, eliminating the frustration of stuck or uneven wheels. The locking casters are easy to engage with a simple foot press, and the release requires minimal effort.

No modifications or additional hardware are needed for typical socket-based installations; simply remove the old wheel, insert the new stem, and secure with the included retaining ring. The materials used are selected for extended outdoor use, with UV-stable plastic that does not become brittle after seasonal temperature changes. These casters are a practical choice for grill owners seeking an affordable yet reliable solution for repair or upgrade.

The set offers consistent performance over time, with the locking feature providing added safety when the grill is placed near flammable materials or on a windy day. While not intended for heavy-duty industrial applications, they meet the needs of residential grilling and occasional tailgating. The solid construction and straightforward design make them a sensible replacement part that aligns with the original equipment specifications.
