Chain-Operated Wheels for Overhead Valves

Open and close almost any hand-wheel operated overhead valve from the floor. These wheels can also be used to operate hatches, skylights, and other overhead components. Use these wheels with galvanized steel lock-link chain (not included). Incorporate a chain container (sold separately) to keep work spaces safe and organized.
Iron hand wheels are durable. Those with a galvanized finish provide corrosion resistance.
Aluminum hand wheels have mild corrosion resistance, are lightweight, and are nonmagnetic.

Impact-Resistant Chain-Operated Wheels for Overhead Valves

Made of high-strength ductile iron, these wheels withstand impact better than other wheels to open and close large or stubborn overhead valves from the floor. They can also be used to operate hatches, skylights, and other overhead components. Use these wheels with galvanized steel lock-link chain (not included). Incorporate a chain container (sold separately) to keep work spaces safe and organized.
