NRG harness length?

[Lumpyguy]

Does anyone have NRG seat harness? I have run my shoulder harness over the rear horizontal square tubing that the roll bar mounts on and shortened the harness as much as I can but It is way to long. I am gonna fab a welded bar in to attach them to but the harness will be down by the front of the engine!?!

my question is does anyone have the NRG 4 point cam lock harness and did you have this problem? or is there a fix? belt shortener?

Just cut it, loop it through like the pic below and then burn the ends of the nylon to keep it from fraying.

I mounted mine similarly.

I also have the NRG harnesses. I removed the attachment hardware that came with them and used eyebolts and clip-ins for the lap and sub straps (fairly cheap from Jegs). I'm not sure if I'll install a harness bar for the shoulder straps, or attach lower like Bob. As you found, there's more than enough length for the shoulder straps; after properly securing, just cut the excess and leave at least 4" past the 3-bar slide. The graphic Erik posted comes from the Schroth manual (http://www.schrothracing.com/sdocs/2009_Competition_Instructions.pdf) which has a lot of good diagrams for properly locating the anchor points.

Much easier to shorten than lengthen!

When you cut them off, can you melt the ends to keep them from fraying like nylon rope?

I haven't trimmed mine yet, but that was my plan.

Yup, I cut mine as well. Mine are bolted to the chassis. You can burn the ends, but mine still fray a bit. I'm not too worried about it since there is sooooo much extra slack.

Hi Guns,

I'm contemplating drilling the square bar like you did as another mounting option. How did you get in there? Access is so tight around the roll bar and other frame members! I have right angle adapters for both my Dremel (which could drill an accurate pilot) and a 3/8" drill. However, the hole needs to be 7/16", so cutting a bit down won't work and I can't find a 7/16" stubby bit with 3/8" shank. I'm thinking that a close quarters drill and short step bit might work, but that would need access from both sides, obviously. Is that how you did it?

Thanks,

Lee

I did the same and drilled from the bottom up.

[wleehendrick]

Yeah, there's just enough room to get in there from the bottom side, with a short enough bit (and 90degree or close quarters drill), but the only 7/16" I can find short enough is a step bit, which would also have to go in from the top, since I don't want to open the hole any more. What bit/drill did you use?

[GUNS]

I drilled through the top w/ a pilot hole and then drilled w/ the 7/16 from the bottom.

Did you find a 7/16" stubby bit with 3/8" shank or have a close quarters drill? This is driving me crazy as I can't find the right combo of drill/adapter and bit that able to get in there... I'd really appreciate it if you or Jerome could point me to what specifically worked for you. Thanks!

use a step drill bit, it is short.]

Yeah, but a step bit requires access to the top of the tube if you don't want to oversize the bottom hole. And there is very little clearance on top of where the inboard hole need to be drilled (not enough for any tools I have). I've ordered the smallest close quarter drill I could find, but I'm really curious as to how Guns and Jerome got in there.

[GUNS]

I have a relatively small drill, but it was still a tight fit. I did have one hole that didn't turn out perfectly straight.

[wleehendrick]

Yeah, been there with 'not perfectly straight' a couple times. I ordered the lowest close quarters drill I could find, since neither of my drills can get in there, even with a right angle attachment. Hopefully it'll fit with a step bit. I just got all the other points drilled for the harness, so next weekend I'll get to the shoulders. Would be nice if I had the capability to weld a bar in, but I think I'll make do. Thanks!

[JeromeS13]

I believe I may have used the step bit on the bottom to get the correct size. Once that hole was created, I switched to a regular bit from the bottom.
