    ZRa Reinforced Frame

    Can anyone tell me the difference between the standard ZRa frame and the reinforced version?

    I flat out beat my chair, so strong is good. But I don't want a big weight or performance hit. I also don't like ugly chairs. What do they reinforce, and what is the upside/downside of this option (other than the extra cost).

    I have not seen a tilite rigid chair with reinforced frame yet, but I'm guessing they add another cross tube under the seat to make the frame more rigid. For an L frame, thats the only place they can weld another tube for rigidity.

    I believe the reinforced frame has a thicker walled tube frame and higher grade bolts...The frame itself doesn't look any different. The bracket for the backrest may be different, I"m not sure...

    This is what was described as a TR reinforced frame on the shipping form (warranty replacement)....



    Some tubing welded into the backrest mount holes.

    So that this wouldnt occur with a bare hole just drilled through the tubing...



    But there might be more to it than that, I dunno.

    Thanks all. I emailed TiLite, but no response so far. I think I'll give the TiLite factory rep I talked to in Orlando next week.

    The reinforced frame is a $300 upcharge. I would hope it was more than a sleeve for the backrest bolt.

    This is an old thread but I got this message from a dealer I'm working with who contacted Tilite:

    I have some additional information from Tilite. The reinforced frame is a thicker tubing wall adding about a pound to the chair.
    Required option if you do power in the future and don't want to void your warranty.

    My AeroZ has a reinforced frame. To me the reinforcement is not apparent.
