RACK AND PINION
The rack and pinion connects the vent to the drive unit shaft. As the drive unit turns the shaft, the rack pushes the vent open or pulls it closed.
Take advantage of Wadsworth’s 40 plus years of experience in automating vents. Our drive units set the standard for powerful performance, smooth operation and reliability.

- The PowerRack arm and housing are manufactured using aluminum alloy for strength and freedom from corrosion
- Wide load-bearing surfaces
- Replaceable parts
- Lubricate pinion gear annually
- Unique design prevents binding
- Wide housing allows for vent movement
- PowerRack’s precision-cut teeth minimize sharp edges, supporting smooth operation
“We installed both of our curtain systems ourselves, one 7-years ago, and one 3-years ago. Each is 120’ square coverage, and both are still taut. The clips are a good system. The curtains save on our heating bill and keep the heat lower to the ground, near the plants, where it should be.”
“We were tempted by another curtain system. But we didn’t want to risk it. We have a long relationship with Wadsworth, and we knew we could trust them to deliver a great system. I’m happy we went with Wadsworth – they take care of us.”
