What Length of Rack?
FEATURES
- Zinc pinion gear with shoulders to bear the weight, extending the life of the gear.
- PowerRack arm and housing is manufactured from aluminum alloy for strength and freedom from corrosion.
- Our zinc pinions and aluminum rack work together to reduce the need for lubricants because zinc and aluminum are natural lubricants.
- We strongly recommend lubricating your racks once a year using Magnalube. This maintenance step can greatly extend the life of your system.
- Precision cut teeth on the PowerRack arms minimize sharp edges and assure smooth operation.
- Holes in the pinion housing are punched with a stamping tool to maintain exact spacing.
- Wide load-bearing surfaces
BENEFITS
- Excellent alignment, works even when the vent is not perfectly square. Our wide housing allows for the inevitable movement in the vents. This unique design prevents binding.
- Freedom from corrosion: Stainless clevis pins, cotter pins, set screws, cast sash brackets and tough nylatron bearings.
- Replaceable parts
- Economically priced
