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.

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.

Overhead Door Openers
Pull a chain (sold separately) to manually open overhead doors. All of these openers have a machinable hub so you can mill the exact bore size you need.
The chain listed is designed for use with these openers—do not substitute other chain. The chain that's not rated with a capacity is for opening, but not supporting, the weight of a door—use it on doors that have independent supports.
