M-2728 Wadsworth Power Rack 28" Straight 1 5/8" OD Shaft
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. Rack is placed every 6′ – 7′. Allow for 6″ of rack when the vent is fully open. All models have 6″ of rack movement per revolution of drive shaft. Straight rack is used in most applications - Curved rack gives extra clearance when space is tight.
- Zinc pinion gear with shoulders to bear the weight and extend the life of the gear
- Easy alignment: racks work even with vent is not square
- Freedom from corrosion – stainless clevis pins, cotter pins, set screws, cast sash brackets and tough Nylatron bearings
- Holes in pinion housing are punched with stamping tool to maintain exact spacing
- The PowerRack arm and housing are manufactured using aluminum alloy for strength and freedom from corrosion
