window net requirments
 

I am upgrading from a roll bar to a roll cage in my bracket car. The car runs in the 10.50's @ 128 with no immediate plans of going much faster. With the upgrade to a roll cage and knowing that the car does not require a cage, will I be required to install and use a window net? I thought the rule book (General Section 6:3) was sort of vague stating that any car REQUIRED TO HAVE A CAGE must use a net.

So if I don't need the cage but put one in anyway do I need the net? I guess it would be a good thing to have regardless but any clarification would be helpful, thanks....

Re: window net requirments
 

You have to run 9.99 or faster to need a net.

Re: window net requirments
 

So the ET is the trigger for the net despite wether or not you have or need a roll cage?

Thanks...

Re: window net requirments
 

If your class does not require a cage, license, and multi layer suit, and you run slower you do not need the window net.

Re: window net requirments
 

Faster than 9.99 OR 135 mph...............

Re: window net requirments
 

I almost got bounced at a super chevy event for having a window net out of date on a 10 second car, no cage cert, no license, no dialing in the 9's, they still busted my stones.

Re: window net requirments
 

You didn't even need a window net. Should have just teken it out. Probably some local tech guy that didn't know what he was doing.

Re: window net requirments
 

Section 20 page 29 in the 2011 NHRA rule book General Regulations,
6:3 Window Net: A ribbon type or SFI Spec 27.1 mesh-type window net is mandatory on any full-body car required by the rules to have a roll-cage.

I interpret that as saying, If your car doesn't require a roll-cage, dont install one!
If you choose to install a cage, then by the "rule" you're required to have the net!

Better to have it & race than not have it & go home!

Re: window net requirments
 

A ribbon window net doesn't expire as told by D3 Tech last year at Indy, but if it says IMPACT on it to get rid of it (rom the Indy div tech inspector).

Re: window net requirments
 

Ribbin type nets do not expire for some unknown reason, but mesh type must be replaced every 2 years.
By the rules ,you must have a net in any car equipped with a full cage ,REGARDLESS of how fast you are going.

Thanks to every one for the replies.
Here is the email exchange I just had with D1 Tech Director Ryck Campbell -

Hello Ryck - I have a tech question. I am upgrading from a roll bar to a roll cage in my bracket car. The car runs in the 10.50's @ 128 with no immediate plans of going much faster. With the upgrade to a roll cage and knowing that the car does not require a cage, will I be required to install and use a window net? I thought the rule book (General Section 6:3) was sort of vague stating any car REQUIRED TO HAVE CAGE must use a net. Any clarification would be helpful, thanks....>> Joe Grippo

Joe, If a roll cage is not mandatory then neither is the window net. Remember that the roll cage requirement for full bodied cars with tops is 10.00 et or 135 mph and for full bodied convertibles is 10.99 et or 135 mph.>> thanks,>> Ryck Campbell

Thanks for the quick response Ryck. So, even though based on et, the car does not need a cage but I am putting one in anyway, I am not required to have a window net.Thanks so much for the clarification. Joe Grippo

Joe, That's correct, if your car has a roof and you don't go quicker than 10.00 et or faster than 135mph. If you are racing a convertible, that it's quicker that 10.99et or faster than 135mph. Ryck Campbell NHRA, Northeast Division Technical Director

That's exactly what I was told.

Re: window net requirments
 

I have been told exactly what Ed said. If you have a cage but its not required
based on class or et then you don't need a window net.

Re: window net requirments
 

I believe this is another of those rules
that are at the discretion of the tech guy
or gal at the time.

We must of had the same tech guy as Terry Cain.
I was told that if the car has a cage it has to
have a window net regardless of et.

Re: window net requirments
 

I'm suprised by Rycks response,but I guess things change.
Several years ago I built a Stocker with a cage for a class that did not require one , the owner was told at that time he had to use the window net regardless of how fast he was going.
Regardless ,I would want one anyway,when properly installed they really aren't that bad. ...Especially the mesh type. ....Whats an arm worth now days?
[ except mabe a tank of gas!]

Re: window net requirments
 

Probably right. I was just looking for clarification.
I have already bought one so I'll probably use it....Better to have it and not need it....
Thanks again for the replies guys....

Re: window net requirments
 

I'm glad this thread was started because I bought a stocker that has a full cage and window net. I asked the previous owner about the net and he said he never used it and no one ever said anything. With all the different responses, I'm still not sure if I have to use it. Guess I'll ask Travis at Indy divisional.

Re: window net requirments
 

I run SS/JA, I have a cage that is certified to 8.50. Not required in my class, nor is a net, multi layer suit, neck collar, gloves or license, unless I run nines or 135 MPH, or move up to SS/IA. I race everywhere, both associations, never one word said about the net not being installed. It rides in the trailer with the neck collar.

Re: window net requirments
 

I have to agree with Ed, I run in Division 1 and 2, Lucas and Nationals, I have a cage no net in SS/MA, no one has ever said I need a net, just went through tech at the Gators today, again no problems.

Re: window net requirments
 

My understanding is that a cage does not automatically require a net. If it did, why aren't you required to have the rest of the safety gear a 9.99 or 135 triggers as that's when you need the net?

In the same vein though, I've seen tech tell people with a roll bar in a car that runs high 11's they have to run a 5 point harness. Take the bar out and your 40 year old seat belts are good to go. I really can't figure that one out.

Re: window net requirments
 

If my memory is correct, years ago the rule book did indeed say that you needed a net if you had a cage, regardless the ET. Somewhere along the line, that was changed to the current wording.

Re: window net requirments
 

IF you have a window net, don't install it to tight...in case of fire it will shrink and you will not be able to release the buckles, that's bad!

Re: window net requirments
 

I have been racing my Demon for the last fifteen years plus with a full Chrome Moly Cage. It has a current chassis cert. on it and a ETI on it. I, have raced SS/JA and KA plus E/SA to G/SA.......has not had net in it since 1995 (175 Div./ Nat. Races) without an issue.

Re: window net requirments
 

Chassis cert don't have anything to do with the window net. (chassis only)

Re: window net requirments
 

There ya go!

Re: window net requirments
 

Rulebook section 6.3 states "any car REQUIRED to have a roll cage must have a window net"
The key word is required. .....If you are quicker than 9.99 or faster than 135 mph, you need a cage, AND a window net. ....Slower than that ,you dont need the net.

Re: window net requirments
 

Better off to be safe than sorry. I would run the net.

Re: window net requirments
 

I have a roll bar, Aftermarket seat and stock belts in the Duster my wife drives, I have been questioned a bunch of times in tech about not having a harness but they always end up letting us thru. I should probably put a harness in it for her but I'm to cheap to throw away new belts every two years for no good reason. Those stock belts are 38 years old now and have never been used, LOL.

Re: window net requirments
 

Not trying to jack this thread, but if the car has a cage that was previously cerified and is not required to have a cage do you still have to get it certified every 3 years?

Re: window net requirments
 

No....... At least, that is my interpretation of the rules.
