The curved PowerRack rack & pinion is designed to give additional clearance when space is tight behind the vents. When a straight rack might interfere with a curtain system or aisle, growers find the curved rack to be the answer.

The simple design is perfect for growers that need extra clearance. And like the straight PowerRack, it is built to last. Virtually maintenance free, the PowerRack is a solid, reliable unit. A rack and pinion you can count on.

The PowerRack is economically priced without compromising on features. Just look at the features we built into our curved PowerRack rack & pinion.

Can You See the Difference?

Succesful growers can. It's the unrivaled quality built into every PowerRack rack and pinion. At Wadsworth Control Systems we know that nothing in your greenhouse takes more abuse than a rack and pinion on a vent. That's why Wadsworth built a solid, reliable rack and pinion you can count on.

While some rack arms are dry cut, the teeth on Wadsworth's PowerRack arms are cut under an oil bath to minimize sharp edges and assure smooth operation. The holes in the pinion housing are punched with a precision stamping tool to maintain exact spacing. We don't compromise quality on even the littlest pin. All clevis pins, cotter pins, and set screws are made of quality stainless steel. And we don't stop there. Every PowerRack arm and housing is manufactured from aluminum for freedom from corrosion.

The PowerRack is built to operate your vents reliably, so you can concentrate on growing. When choosing which rack and pinion to use, consider reliability and savings on maintenance costs. Wadsworth's PowerRack is the most economical rack and pinion on the market today. Look closer at the PowerRack and you'll see the difference!
