Heavy Duty Lubricant | #400-HD
is backordered and will ship as soon as it is back in stock.
400-HD National Door Lube is 15 ounces of aerosol lube that stands out in its class. This heavy-duty, non-silicone lubricant is ideal for all garage door and operator requirements and has become a go-to for garage door service companies. 400-HD efficiently penetrates frozen components, threads, bearings, and all kinds of metal surfaces; it also helps to avert rust, corrosion, and dust/dirt accumulation that can obstruct the performance of garage doors and operators. To apply, simply use the specified 3-way nozzle, which adjusts from high, medium, and low-intensity spray.
Had my garage door serviced by a specialist company. I asked what lubricant did he recommend and showed me a can of the 400-HD. He was correct in that it is more expensive than what you can buy in stores, but he swore by it and won't use anything else. I recently cleaned the tracks and rollers with Brake Kleen than lubricated all the contact areas with 400-HD. Works great so far and doesn't appear to attract dirt or create greasy build up. The can says 1 application is good for a year, so time will tell.
This product is the best there is out there. I shit you NOT it is good stuff and does not make a mess. Love the adjustable nozzle too. I will never use anything else.
Thanks,

The product arrived on timely. I ordered this product based on the advice of my garage door installer and this product works great. No more squeaky noises. I applied it to the spring, hinges and the rollers and the track with amazing results. I am very pleased with the product. Highly recommended door-parts.com for all your garage doors needs.
This is the product the garage door company that services our doors uses. It works very well to lubricate rollers and hinges on the doors. They are so much quieter after application of this product. I purchased to use on the garage doors and other things around the shop.
Great product for keeping garage doors lubed and smooth running. Shipping was a bit slow but I had some of that same lube left in a can my garage door guy left me so I didn't need it to come fast. Reasonable price and that can will last a couple of years. Vvery satisfied.
