The first thing you need to know about a strut is that a garage door strut manufactured at a garage door company is your best protection against bending a section. Thing you need to know is that a piece of punched angle only comes in 8 foot pieces so if your door is a feet wide or less then yes you can use a piece of punched and go as some sort of protection against bending the top section of your garage door with an opener attached to it if your door is bigger than 8 feet then this will not work you can not put two different pieces of punch dangle on a garage door and expect it to protect the section from bending because it needs to be one continuous solid piece from left to right hand side of the garage door so if you need to use one of these pieces of angle then make sure you screw it into the left and right hand side of the garage door styles and do not forget to screw it into the middle style also this will give it maximum strength. You must remember that the angle that you would get at Home Depot or Lowes is usually a lot thinner gauge of steel then the options that a garage door company would have at his supply warehouse because they usually have two to three different gauges to choose from and the thicker the gauge of metal the more strength you will have.

garage door bigger than 8 feet

If your garage door is bigger than 8 feet wide and you will probably have to call a garage door company to come and install a strut for you since I have not seen a garage door strut at Lowes or Home Depot available to the public. Ever seen people use other things as a strut like a 16 foot two by four but even though it will serve a purpose it is far too much weight to add to the garage door so you have to be careful about using anything other than a garage door strut for a door that size because adding weight to a garage door means that you can make it unbalanced without even knowing it.

8 foot garage door

A single 8 foot garage door and you do not have an opener attached to it then you will not need a strut this truck is crucial for an 8 foot single door with an opener because the constant pulling on the top section from the open air will definitely be in that top section in and cause problems down the road you would probably have to replace that top section eventually if you do not attach a strut to that top section. You have a 16 foot wide garage door then it is necessary to have a strut on the top section because when the door is in the up position if it does not have a strap on that top section it will sec and eventually cause problems down the road so that’s why all 16 foot garage doors need to have a strut on the top section even if you do not have an opener attached to it. Door is wider than 16 feet then you should have a strut on every section of the garage door. 4 giving some extra strength to a garage door panel that has cracked or bent and needs to be rejected again so that the garage door can function properly when opening up and down if there is a band or crack and it allows the section to sag when it is in the up position then sometimes it will keep the door from closing all together so adding a strut or two to a garage door to fix a panel is a easy fix without having to replace the whole garage door panel. Also a grudge door strut does not weigh very much at all so adding one or two to your garage door should not affect the weight of the door too much so you would probably not have to adjust the spring system to make up for any added weight. Had to put a strut on every section of your garage door then you would probably have to adjust the spring system because that many strides will definitely add a significant amount of weight to the garage door and make it a bit heavier.
