Frequently Asked Questions
The same size as your door. The door fits against the opening from the inside. The opening should be finished with an exterior perimeter seal or stop molding to seal against the elements.
Any product with tri-sodium-phosphate (TSP), such as Soilax„ or diluted Spic-n-Span. In areas where there are TSP restrictions, use a mild household cleaner. All products should first be tested on a small interior surface to ensure color fastness.
Steel doors should be painted with a high quality exterior latex (water base) paint. The surface must be cleaned prior to application of paint to the steel. On new doors, the surface just needs to be wiped down with a damp cloth. Doors which have been installed for a while should be cleaned with a tri-sodium-phosphate based product (such as Soilax„ or diluted Spic-n-Span or a mild household cleaner). Doors do not require a coat of primer unless the finish has been damaged down to the silver galvanizing.
Generally a 1/3 horsepower opener is sufficient for any single car doors and a 1/2 horsepower for some of the heavier double car doors. The door must be reinforced prior to attachment of a garage door opener (please refer to the manufacturer’s instruction for more information).
Doors with extension springs require 10" of headroom while doors with torsion springs require 12" of headroom. If installing a garage door opener, you will need an additional 2"-3" headroom dependent upon the manufacturer of the opener. Low headroom hardware is available that can reduce the headroom requirement to as low as 4".
Yes. The lower the gauge, the thicker (and stronger) the steel (ex. a 24 gauge steel is thicker than a 27 g. steel).
Yes. Our residential garage doors are available in sizes ranging in width from 4’2" up to 20’ in 2" increments (our commercial door line offers widths in excess of 20'). Door heights are available beginning at 6’ up to 8’ in 3" increments (excluding a 7’3" – heights in excess of 8’ are available in our commercial line). Not all models are available in all sizes.
Yes. If we still manufacture the model number door you have, replacement sections are available through your local retail store or professional installing dealer. If your door was manufactured in the last 8 years, we can identify the model number of your door by the 15-16 digit serial number on the interior bottom section of your door. Exposure to the elements over time will alter the color of the section, therefore it may not be a perfect match (we also changed the color of white in April 1994).
We recommend the following maintenance be performed on an annual basis (please refer to the installation manual for a detailed description of the maintenance requirements):
- Clean door surface with a mild household detergent and rinse with clear water (best if done twice a year)
- Lubricate all moving parts of the door with light household oil (e.g. WD 40)
- Check for bent or loose hinges
- Check rollers for broken wheels, bent shafts or worn out bearings
- Check the door and track supports for loose or missing bolts, screws, etc. and tighten.
- Check the extension spring lift cables for proper operation (are they running properly in the pulleys, is the cable rubbing at the bottom bracket button location?)
- Check for bent track
