Bolt in Harness Bar don't do it!!!

Here you want PROOF that thing is a pile o'****?

Straight from the auction with some VERY relevant issue in bold...

-----------------------------------------------------------------------
Made of lightweight steel (LMAO - that's a good one!)

Length of harness bar (overall / adjustable hole-to-hole) = 50" / 47"-52.5"
Length of support rod (adjustable hole-to-hole) = 27.5"-28.5"
Weight of harness bar / support rod = 6 LBS / 3 LBS
Depth of harness bar (overall) = 13.5"
Diameter of harness bar (hollow) = 2.5"
Gauge of harness bar = Unknown
-------------------------------------------------------------------

The wall thickness of the tubing is UNKNOWN

Are you fricken kidding me!!!

Now taking the info from above we can roughly calculate some interesting tidbits about the item.

Let call the harness bar 2.5" diameter, 50" long. Additionally it has clevis slugs and other items welded to it. The info states that it is 6 pounds and the support rods are 3 pounds. The support rods are insignificant here so disregard. Lets allow the total weight of the bar to include the clevis plugs/tab because it benefits the thickness calculation which is counter to my claim that it's a pile of junk.

You can go to a metal supplier and get the weights for materials in all shapes and sizes. Some online suppliers have calculators. Here's a good one. http://www.onlinemetals.com/calculator.cfm

Using the 50", 2.5 diameter and inputting various wall thicknesses, a wall thickness of .060 comes up to a weight of 6.5 pounds. Keep in mind we included the clevis weight so the ACTUAL bar thickness is THINNER than the .060 input. If the bar running length is longer than 50", it makes the tubing THINNER.

Minimum roll bar tubing wall for NHRA using CM is .083. That thing isn't CM...

Nice muffler tubing harness!

Go chew on that for a while.
