    "Bro, do you even
    1. CAD model?
    2. Finite element analysis?
    3. Understand basic principles of pressure, force, mechanics, and tensile strength?"
    I'll have what you're having....

    So if you had 2 of these mounts on the front of the chassis somewhere and use a bridle between the snatch strap and the webbing recovery point, what would your analysis look like then?? To be fair, if you look at the photos the real plate has more meat on it at the slot, which would make it a bit stronger too.

    Something in between the linear and 90deg tests. They are not designed to be side loaded in any way. They are a VERY poor device for this application. PEOPLE HAVE DIED USING THE WRONG EQUIPMENT FOR RECOVERY. Some of these people spend mega bucks building vehicles with all the brand name gear and then scrimp on recovery equipment.

    Do I build my own stuff. Hell yes, but nothing that hasn't been tested to destruction (bit wasier now with FEA). For example, the pin that goes through tow bar insert. They apparently can be used to put through the eye of a strap. Personal test bed results have them bending below bar rating (with strap). My own pin (4140HT steel) will rip the bar apart (not catastrophically) at 4+ x bar rating. is std size, used for both straps and tow bar insert.

    The D2 bar is a work in progress, will be FEA'd and possibly destruction tested too.

    Don't stress, I just emailed the tests to the manufacturer to see what they say. Of course all results are simulations, but the CAD used Aust and other standards for material and fasteners and other stuff correlates to results.

    Last word: If you were stuck on a beach with a raging rising tide I'd move up the beach and give you a beer as we watched because unless you had ten of these things bolted to appropriate holes (individually) you'd not get me to put a winch rope on it let alone a snatch strap, which I never use. But thats another debate.

    Depends on the distance apart. Part of me wants to ask how good is your trigonometry. The other part wants to say - even when tested in the *best case scenario*, the device still failed simulations at what the manufacturer claims they were rated.

    Choose appropriate parts for appropriate tasks.

    It (the strap) is a TOW recovery point...

    Even thinking of recovering off that other than towing it very very very smoothly, without the webbing being wet, and no dirt / grit in the webbing... Is just foolish...

    Why is this even being debated?

    Not fit for use other than on a race track..

    My idea to look at it, seems too obvious really, if it were to be strong enough?? Its an 1/8th the cost of anything else sold as a recovery point if it works, I'm just putting it up for discussion?


    Also because LRSolutions UK sell them as a Land Rover Defender 4X4 towing recovery eye point, "Ideal for off road as flexible and easy to attach to. These are quality items made in the UK by seat harness manufacture 'LUKE' This MSA compliant tow strap from Luke is suitable for fitting to the front or rear of the car."


    Thought it was worth looking at is all....

    As a ******TOWING****** recovery point...

    Perhaps LR Solutions has decided that a race track application will translate to offroad kinetic recovery... Doesn't mean they got it right!

    OK

    Here's some examples of what goes wrong when the right stuff is used by idiots.

    And remember this first video is a paid crew making a TV program.
    LiveLeak.com - 4x4 Recovery Gone Wrong (comments)

    This one is graphic but shows perfectly something rated being used incorrectly.

    Coroners Report into Snatch Strap death


    We're not here to poo poo. We just want people to do it safely and stay alive. There's a reason I'm 43 and still alive after 40 years doing this. And that included growing up being winch bitch when there wasn't a heap of education and knowledge and testing. It was really just well if it looks good enough then whatever you made in the backyard was good enough because there was no aftermarket supply chain. And even then, I get bagged for using 6.5T shackles (19mm yellow pin) when everyone else buys the 3T green ones off the shelf because if thats what they sell... But I know each part of my gear, it's margins and safety factors and even at double potential load from the winch, using a pulley it's still over engineered.

    If it's just because the manufacturer says...I've got a lovely bridge I knocked up in '32. Lots of users, great harbor views. Only one owner.
