Aluminum Rack and Pinion

Check up to five results to perform an action.

Rack and pinion connects the vent to the shaft. As the drive unit turns the shaft, the rack pushes the vent open or pulls it closed.

What type of rack should I use?
  • Curved Rack can give you extra clearance when space is tight and the rack might interfere with a curtain or aisle
  • Straight Rack is used in most applications
What rack material do I need?
  • Aluminum Rack is used in most applications
  • Steel Rack is generally used for open roof greenhouses that need extra strength
How is the rack spaced?
    Rack is usually placed every 6' to 7'. There should be 6" of rack when the vent is fully open. All models have 6" of rack movement per revolution of drive shaft.
Features
  • Zinc pinion gear with shoulders to bear the weight and extend the life of the gear.
  • To extend life even further, lubricate once a year with Magna Lube, White Lithium Grease or a graphite-based spray lubricant.
  • Wide housing allows for unavoidable movement in the vents.
  • Unique design prevents binding.
  • Easy alignment: racks work even when the vent is not perfectly square.
  • Freedom from corrosion: stainless clevis pins, cotter pins, set screws, cast sash brackets and tough Nylatron bearings.
  • Precision-cut teeth on the PowerRack arms minimize sharp edges, assuring smooth operation.
  • Holes in the pinion housing are punched with a stamping tool to maintain exact spacing.
  • The PowerRack arm and housing are manufactured from aluminum alloy for strength and freedom from corrosion.
  • Wide load-bearing surfaces.
  • Replaceable parts.
