Throwing this out there. I have been reading and reading and reading about cages most the summer. I plan to start a project in January(ish) involving my YJ. I am currently in the process of trading for a family style roll bar but I want to turn that into a full cage.
The one thing that I have not come across is, Has anyone designed a cage with the rear seat in mind and it capable of holding two child car seats??? I have not found very many writeups that include the rear seat. My goal here is to be able to wheel it in the future with the rug rats in the back but also be able to use it as a DD for now while they are younger and still be safe. The dilema I see is, the space needed to gain access to the seat to buckle them in and past he seat thru the frame.
Any ideas, suggestions or pics of cages fabed up in this manor would be great. Thanx guys.
Congenital Heart Disease is a reality for me, BOTH of my children have it. Please read up and become aware for future generations

Nice work but you missed a spot with the spraypaint. The gray cage and frame you referenced is mine. As Zach said the X being 2" behind the b-pillar has not been a problem at all. I just rolled it again this weekend, still fine. The X mounts to the frame over the wheel wells. Your design is fine too, I just wanted to be able to unbolt it all instead of removing with a sawzall.
Cage in my '99 TJ, It's a through dash design. 6 point frame tie ins. The frame tie-ins are welded to the frame and then bolted through the tub. It used the stock main hoop and rear bars. I know this really isn't a super hardcore design but it met my needs, considerable increase in protection over a stock cage, Ease of entry/exit. Headroom for front and rear passengers. This cage works with my stock Hardtop or softop. I have my son riding in the back on some trail rides and we feel he's a lot safer now that we've put the cage in.
Do you have any trouble putting the soft top on? And did you basically weld or bolt on new tube's to the existing roll bars?
Hey guys I was surfing on here and just found this thread.
I didn't read 15 pages but I flipped through them. There are some GREAT designs on here for cages. I too just did my cage. My first attempt was given to me from a frien who competes. He rolled over backwards and it tweaked the cage enough I didn't want to use it but it is being used in a jeep now.
This is my current cage:
I know some folks don't agree with re-useing the stock center and rears but thats what I did on both my cages. They are fully welded (even the bolted sections of the stock cage are welded). The front and rear came from TrailWorks in Nashville, TN and The 3 braces in the rear and the bottom windshield spreader I added. There are also braces along the floor board that I added. I know alot of people insist on DOM for cages too. We used HREW on the second DOM on the first. I did alot of research and re-useing the stock center with DOM additions is not totally benificial. The stock Cage portions are HREW and therefor the weak link. By braceing it and makeing the rest from HREW it distributes a hit a little better. Right now just the front two legs are frame tied, but when I finish it will have 6 frame tie-un locations. I am also going to add a few gussetts and grab handles.
I know this isn't the greatest cage in existance but I definatly feel safer with it!!!!
I had a really hard time finding just the floor mounts to start my new cage so with the help of Copperhead fab we got some publically available now. I got the prototype brackets back from Copperhead Fab today and they fit great. I am having them change the small tab plates on the B Pillar for the production versions they are going to sell. We are going to make them with two slot holes instead of the single slot and round hole. I did have to take a die grinder and open up the round hole a bit and the slot will take care of that issue and make it more suitable for mass production allowing a bit of tolerance to tub changes or slightly tweaked bodies. The side plates weld above the bottom B Pillar plates so I have no worries about strength in this area over a bend bracket like Poly Performance uses. The problem I found is that there was no company I could locate that would sell just the mouting plates. Now Jeepers will have a source for these. I will also design some front A pillar plates once I get to bending tube.
I think the 6 piece mount set will sell for about $19.99 and by the time this project is done they will be offering more options such as the frame tie in plates that I have yet to design.
**If anyone has some links to frame ties in done in the B pillar of TJ it would be much appreciated. The body mount and tub channel run under and to the front of this area so it is going to take some design work if I want to keep the tub factory and not cut the channel out but I think it is possible with some creativity.**
P.S. The B pillar mounts are just tack welded at the moment. I want to wait until I go up to Copperhead to use a mig with a bit more heat then my 110 volt home unit.
I also welded a bolt on my POB bracket and installed a jam nut so I can use the new Craftsman digital level when bending tube and do not have to worry about knocking it off which happened a few time with the old level.
FYI the digital levels are on sale right now at sears. I got this one because the built in laser is great for measuring out the cage design. This one was regular $49.95 down ot $34.95 the cheaper one was about $29.95 on sale.
