How is this done? If the hoop comes to the outer edge of the Blazer do you run a bent tube from the plate to the frame and weld or bolt to the frame?

I'm confused... anyone have pics? :doah:

From the mounting point of your cage inside the cab area, you of course want to have a backing plate underneath the vehicle thats larger then the cage mounting plate. Yes you weld a bent tube to it that bends and goes inboard towards the frame and has a bushing tube welded to the end. Then you bolt or weld a cleat with tabs or weld gusseted tabe to the frame that will accept the mating urathane bushing with a bolt & nut setup. This setup will be removable if you need to remove or repair the cage for some reason. Some have pics of this setup, but I don't, sorry. Try searching frame tie ins or something like that, you should find what you need.
 
thanks Dave... and mine aren't even done yet..... :doah::o


OP, here's my understanding of it, take that with a pound of salt.... :crazy:

2 approaches....

hard mounted to the frame... this can be approached a few ways, from just cutting holes in the floor and bringing tube right to the frame. to a baseplate/flange method, or even better, a staked flange method...


here you can see how the bottom mount for a staked is, without the bottom plate...

the bottom plate has a shear lug i'll call it, that goes up in that hole... than, on a hard mounted setup, you can just bring tube over from the bottom plate and weld it to the frame...


second way of doing it... maintaining a system of body mounts, i'll call it.......

I'm doing mine as mentioned above, but instead of welding tube to the frame, i'm gonna run tube over to these bolted to the frame...

This is exactly what I described and was talking about. Not sure who makes these though.

it's got Kert's name written all over it... :whistle::whistle:

I need a few more actually for a project up front... I only bought 4 that time, and it was like 150 smackers.... :doah::o I need another 6... :crazy: :doah:

No doubt, and I bet he will do them at a far better price. Going to contact him on them, see if he can do them.
 
I have a part drafted. Backward engineered to be compatible with our existing staked cage floor plates. I'll have to see if I have a punch and die short enough to do the job. Punch I think is no problem.

Everytime I've seen these used, it seems to me the axis of the bolt needs to be rotated 90*. It would appear they are mounted the simplest way but not necessarily the best way. Only way I know to describe it, with the bolt one way its a hinge. Bolt the other way its more likely to be a supporting piece. This is considering the force applied from the direction of the cab toward the frame. I think that is the most important thing to consider for this particular piece.
 
Thanks for the replies guys!

Kert, maybe i was thinking along the same line. It seems that the purpose of these is to prevent the cage from coming crushing through the floor board in case of a rollover. The way these are designed it looks like they would pivot if force was applied to the top of the cage and kinda defeating the purpose.

Am I way off? School me.

Kert, i contemplated talking to you about these when i ordered them... i think something incorporated into the staked flanges would be awesome, an option to them or something...

it wont work for me with this style, bolted down at the frame... but if yours aren't too far down the road, i may sell these and do all mine with yours... i'd still put a flange at the frmae end of the tube and bolt to the frame... but i certainly wouldn't mind getting the bushings up under the floor...
 
eh, for something seeing a fair amount of street duty, I don't agree... trail rig, sure...
