Shameless plug for my sons invention on Kickstarter!

They are designed to keep the door shut in a crash, must be pretty stout.

I always just stand on top of the tire, have seen a rig that hangs on the tire to give you a step too.

super slick!! love it.

(i wonder) what happens if you absent mindedly slam the door on it hanging there? that point is pretty burly i suspect, as Tobra points out.

So the hook pulls away from that door catch, not down.

I'de be more worried aboutit pulling the door catch out from the door jamb, or denting the spot where the fulcrum is.

Yer right....I said downward force, but you are correct in what I meant....

IF = WHEN

Maroonproof....just a concept

To the OP...ignore us naysayers.....this is PPOT....it's what we do

i think it is a GREAT idea. i'm a munchkin..and could use the boost.

Thats a very specific and clever product. Good luck to him. Proud dad!

[911boost]

Are they making them yet? I know a few folks I would buy one for......

Maybe they should be painted in pink or orange?
It would be easier to see it before (or during ) slamming the door.

Great Idea! You should be proud. Hope it does well. Just pledged for two of them. Will give one away and keep one for my truck.

[Laneco]

OMG! Just pledged for four of them!

I will reach ALL THE ROOF RACKS! VICTORY SHALL ME MINE!

I think that is a great idea and I'm getting some for myself. Even at 6'-1", Ladder racks and bike/canoe racks on pickups and SUV's can be a struggle. Easy enough to stand on the back tire, but often the cab is the issue, and I don't like to stand on the seat.

[tevake]

Cool idea, should do well at sports shops.
Nice to see your kids doing well like this.

Cheers Richard

great idea!

[Vipergrün]

Thank you all for the kind words and your support!

Yes they are making them and expecting the first batch soon. Needless to say this has far exceeded their expectations, but they are planning on making the dates targeted on Kickstarter.

I may fly back and help pack boxes :--)

Awesome idea!!!!

I would worry about a 300lb dude jumping on that thing, though. The latch is attached to the jamb by a couple of small bolts. Have they done a load test on various vehicles to find the deformation/failure weight? As someone else said, make sure he has good insurance.

[Charles Freeborn]

Great idea. Might even get one after I ask around on whether it'll damage the car (Outback).

Like others mentioned, that latch is what keeps your door closed in a crash. It is very beefy. It takes a LOT of force to take out a bolt:

My only concern would be that the loads are directed in a way that the pillar and latch are not designed to handle. That said, yes, that part of the car is very robust for other safety reasons. Still, a very clever idea. I load lumber and sheet goods onto the roof of my Outback a lot, as I'm in the woodworking biz, so I do see real value in this product.

[Vipergrün]

Thank you all for the feedback!

I'll try to track down a document, from the NHTSA, which outlines the strength and testing requirements for that area of the car. The striker bolt has to support 2500lbs of force.

The device is meant to be used in taller vehicles where the device can hang without interference from the wheel well, or other protrusion. It will come with warning labels, etc
