Window Net Rule

I just recieved this an hour ago.

The NHRA has amended rules regarding the requirement of a window net for some of its sportsman and E.T. bracket classes effective March 5, 2012. The amendment clarifies the requirement of a SFI 27.1 window net in all full-bodied vehicles in Advanced E.T., Top Sportsman, Competition Eliminator, Pro Mod, and Pro Stock. See the Rules Amendments that will appear on
www.nhraracer.com
for individual eliminator requirements.

General Regulations

Section 20, page 29

6:3 WINDOW NET

An SFI 27.1 ribbon-type or mesh-type window net is mandatory on any full-bodied car required by the rules to have a roll cage. An SFI 27.1 ribbon-type or mesh-type window net is mandatory on any full-bodied car running 7.49 (*4.49) or quicker. For full-bodied cars running 7.50 (*4.50) to 9.99 (*6.39) or if vehicle runs 135 mph or faster a ribbon-type or SFI 27.1 mesh-type window net is mandatory unless otherwise specified by class requirements. SFI 27.1 window net, when required, must be updated at two-year intervals from the date of manufacture. Window net must be securely mounted on the inside of the roll cage, with the permanent attachment at the bottom. All attachment points must be designed in an attempt to protect the driver and avoid contact with track surface or guardwall. Eyelet clips, dogleash hardware, hose clamps, etc. prohibited. Penetration of webbing, except as performed by manufacturer, prohibited. Any modification to net must be performed by manufacturer.

Originally it was announced that basically all that were required to have a roll cage were to have an SFI ribbon-type or mesh-type window net that would be required to be updated every 2-years. Basically the 7.50 & slower vehicles (SS, Stock, Super Pro ET, SC, SG & SST) window net rule reverts back to the way that it was with a ribbon-type or SFI 27.1 mesh-type net accepted.
Advanced ET cars 7.49 & quicker, Top Sportsman, Pro Mod and Pro Stock will continue to require a SFI 27.1 ribbon-type or mesh-type window net, to be updated every two years.
