I have one single door; so I would need two kits. How much weight do the panels add to the door? Will the springs need to be adjusted?

One box will cover a single steel car 9 foot wide door double/single door requires two. its easy to install no drilling et just stick and push. As for the additional weight nothing to noticeable and you don't have to adjust your springs. Hope this was of help and read the instructions through... "Good Luck"

I have a single aluminum door. One kit was good and I didn't have to adjust the springs. It works great, big difference.

The weight is insignificant to it because the insulation becomes a part of the door once it is in place. Once you start working with the kit you'll see how weightless it is. One things I would recommend, purchased additional white colored duct tape. Duck tape will hold up the best... just ensure the surfaces are clean prior to assembling to garage door.

I installed these kits in my last two homes and haven't had to adjust anything.

I have a single door that is approximately 9 ft wide. I only needed 1 kit. It did not add very much weight at all.

The weight added is very minimal. You will not need to make any adjustments to your springs or anything like that. Just install and you're good to go!

Probably not heavyweight enough. Maybe if you can do one at the top and bottom and the door is not too heavy

One brace for each panel. I cut mine back because door was smaller. Heavy gauge metal - worth the money. Should do the job. Make sure to secure brace to good chunk of wood support. Wheels on the base of the door will extent the life of the door. That is a lot of wood to support from only side supports. You wnat to do this right the first time and not have to make adjustments in two years. Add support wheels.

When I ordered it, they came as a pack of 2. So if your door has two hinges, you would just need one set per door.

I think that's heavier than these would support. While they are supposed to put out 150 lb of force, the point on the door that they attach is just 3 and a half inches or so from the hinge, so there isn't a lot of leverage. This might give you a better idea of capabilities of the spring - http://www.rockler.com/product.cfm?page=10807

Unsure, I would contact manufacturer. Although the garage door repair co. That replaced a broken spring said our double door was in the 90 percentile of weight in all the door she had encountered. The opener is slower than most, but makes up for it in torque.

I do not think that would be a good idea. The center support bar does not look wide enough to support two individual box springs. Most likely they would fall in the center.

If that's all you need I would try a hardware store like ACE or something. Could save you $18+/-...and I assume you still have the other 5 springs, just take one in with you. I can't imagine the spring tension to be all that critical, just the overall size. Good luck!

Yes it will Tim, up to an extra 1000 lbs. They can be adjusted by tightening or loosening the four bolts on each spring. It sounds like a lot of work but it is so easy I take them off when I am not using them and install when I need them.

Amazon sold my springs as a pair and I've never seen them sold any other way so I'd say yes. I've since upgraded to the heavier series, however. They are holding up well but the lighter series sagged after a few months of occasional hauling. I don't recommend running them anywhere near their rated capacity.

you should only need 2 as the tension is adjustable on the hinges. If the door droops just increase the tension on the hinge

Just one. These are high tension springs made for a metal double car garage. Use extreme caution when installing. Its worth having a door place do it for you.

Just one panel comes with this door. Additional panels would be required for a wider area.

If you install this kit with the included springs I believe your pull will be about five pounds, and much smoother. I think you'll really appreciate the difference this kit makes. If you want to swap in a new set of sights this would be the time to do that too.

It depends. I am aware of at least two different spring systems for sectional doors that slide on tracks. If your current door has two springs attached overhead, near the center of the door then this is probably the part. If your door has springs kind of hanging from the both the right and left sides of the door, then this is not the proper part. It can be dangerous to change the center-type springs if you don't do things in the exact correct order. There are several very good videos available on YouTube that I highly suggest you take the time to review. You'll need to swing by your local hardware store and pick up some spring winding tools (not complicated or expensive). I had to obtain these from the non-national brand stores. I'm only guessing that the national brands don't sell them due to the danger of winding springs. Anyway - good luck.

I have a single car garage door. And it requires only one spring. This one works fine in my case
