JK Auxiliary Roof Rack by MBRP-Forum Special
I love this design.
Couple of observations:
1. If the knobs for the adjustable bars were on the sides or bottom, it would give a larger usable flat surface.
2. If the light tabs were level with the top of the bars, you could then just bolt many of the accessories to the tabs - especially since the center bar is adjustable. I know for lights, the bolt/nuts would stick up. Or you could supply spacers to to the same thing!
Any idea on the lateral force that the side bars can take? What kind of testing did you do, was that a design consideration? (top armor?
)
How do you recommend sealing the joints where to top tubes are joined and where the screws are located?
Again, this has huge possiblities. Great job!

Oh, and shipping to SoCal (91364) would be nice to know...

This rack looks awesome! I think an extension would be great so I could get 2 more bikes up there. How bad would shipping be to 91355 in southern California?
I would be concerned about water getting into the unused holes in the top of the tubing where the center cross bar is attached. It looks like there are 6 positions available which leaves 5 empty holes on top on each side. Is there a drain hole or something? It seems like with the weather you have up there, you would have run across this already.

The shipping has not been confirmed at this time but we will be getting a shipment of Jeep products back from the coaters on Wednesday. I believe we will be working on packaging these racks later this week and should have an idea of shipping costs by this Friday.
I will let everyone know when there are shipping quotes available.

I will pass this along to the designers and see what they think.
As for side weight testing, I will have to look into this. I know the rack is very solid and can not be flexed from side to side, but it would not likely bear the same weight as all of us standing on top.
We have driven this rack through some of the worst weather thrown at us up north and water getting inside the tube has not been an issue. There is a 4" slip joint that has no play at all so the chances of any substantial amount of water actually entering is slim to none unless it were submerged for a prolonged period of time.
Excellent questions...
Thank you for the excellent suggestions. We have already adapted the brackets to come flush with the top of the bars for easy mounting of a platform, or lights etc. That is the first time someone has suggested the knobs and their location but that is a very valid thought.

On my previous rig, I had a ConFerr rack that came in two sections and they used a similar slip joint mechanism. They provided RTV for the joints and the screw holes.

Im sure Steve will be able to update you when he is back in the office come Monday.
We are running a extra Saturday shift today with two guys building more of these right now so we can get another run sent to the coaters and get finished stock on these units here in our facility.
Thanks
