This RaceQuip Window Net Bottom Bar Attachment Kit features an unique way to secure the driver's side window net in a racecar. This kit consists of six drop forged 3 bar slides and six 1.5" wide nylon straps with loops at the top. This "strap on" kit allows you to mount your bottom window net bar to a door bar in the racecar chassis. You install the straps on the bottom bar of the window net mount kit, and then determine the length you need to wrap around a rollbar in the door. You then adjust the length of the straps and then loop them around the bar and lock them in place with the 3 bar slides. It is recommended to use all six straps to replicate the strength of the window net itself. Sold as one complete kit.
