The strut holds it stiff while the door lifts.
How much does a garage door strut weigh.
Struts weigh about twelve pounds for a 16 door.
Otherwise the extra weight will shorten the life of your garage door opener.
It should be noted that since the cable loops around a pulley the lifting force of a 210 pound spring is only 105 pounds as seen by the garage door.
A standard 16 foot strut weighs about 12 15 pounds so the spring will at minimum need to be adjusted and it is not uncommon to have to replace the spring s when a strut is added to the garage door.
Adding a strut to a garage door is adding weight to a garage door with the added weight you may need to adjust or replace the spring s to accommodate for the added weight.
We adjust your spring tension accordingly or we recommend replacing your torsion springs.
Otherwise the extra weight will shorten the life of your garage door opener.
Garage door struts for eight and nine foot wide doors can ship by fedex or ups but longer struts will not.
This prevents any bending of the top panel that may be caused by the opener trying to lift the door up.
If you plan on reinforcing your garage door with extra steel braces you need to plan for weight being added to the door.
Therefore you need a pair of 210 pound springs even though your total door weight is 210 pounds.
Struts add on average 1 lb per linear foot to the door weight so a strut for a double door 16ft wide will add about 16lbs to the total door weight.
If you intend to use a garage door opener to operate your door it is crucial to install a garage door strut on the top panel of the garage door.
If you add two struts it will cause your door to be out of balance.
