      What I find incredible about TiLite's UniLock is that they appear to intentionally orient the handle like that. If you look closely at the hardware, you will probably see evidence that the nut and bolt used to set the orientation of the handle were originally in another hole.

      I have to admit the last time I had our tech "put it back where it should have been in the first place", we ended up changing it back. Turns out the veteran who received the chair wanted it sticking up like that so he could hang his keys on it.

        peter - everything here is metric too - i have quite a few imperial (sae) tools ive bought myself on holidays to the us... can you use an adjustable wrench? or otherwise use the slightly larger one, and tape over the nut with electrical tape (aka vinyl tape). it isnt the best solution, but it is possible. you should retighten the bolt often.

          SCI_OTR - What is the percentage of your clients using the Unilock set to push as compared to pull? Is there any advantage over the other?

          amyk - Thanks for the tip. Worse comes to worst, I will use an adjustable wrench but I am sure I can get imperial wrenches here. Just need to look harder.

            A Much Happier Picture..

            I was wondering how petertan was doing since he hasn't posted here for awhile. I came across the following pic from his blog. To me, it exemplifies what this forum is all about...




            Lookin' good petertan!

                    Looks like I picked a popular chair. I have had my ZRA2 for about 3 weeks now and will post pics this weekend if I get around to it.

                      Hi SCI_OTR, It is good to know that I have been in your thoughts. I have been around lurking but not posting. The chair with its original configurations (/forum/showpost.php?p=1368336&postcount=6) is good but could be a little better with some tweaking which I have not got down to yet.

                      Things I would like to change: Increase seat dump from 3.5" to 4". Adjust angle from 95 degrees to 92 degrees. Lower seat back height from 16" to 15". I would also like to try out a rigid seat pan. The current seat straps slacks all the time and have to be retightened frequently.

                      As you have already noticed that I swapped the stock forks and caster with Froglegs Unitines and softrolls. The softrolls give a more gentle ride over slight bumps. The stock forks were 6.5" barrel to floor but the Unitines are 6" only. Good thing is that my footrest had 3.5" clearance in its original configuration. Minor the difference of 0.5" may be but this is something that should be considered when switching to Unitines.

                      There are also threads/strings coming off the sidewall part of the Schwalbe Marathon Plus tyres that are in contact with the rim. There are also cracks where the sidewall joins the top part of the tyre. I hope these don't cause the tyres to fail prematurely.

                      Generally, I am quite happy with how the ZRA turned out, especially with the recommendations from you and other members of the forum without which I would not have the confidence to buy the chair.

                        On my chair I had to continually tighten them as well but after a few months they seemed to settle in.

                            Brian - I guess my straps have not gone past the settling-in process yet. The back straps are easier but the seat straps need a bit more work.

                            Kenny - Thanks.

                              Another petertan Update

                              What a difference a year makes (even in the exact same chair)



                              http://www.petertan.com/blog/2012/04...-after-review/



                              Your posture looks like how I try to sit the first 1-2 days I'm at a conference where I know other seating specialists are analyzing my equipment and posture! (After the second day it's all down hill!)

                              Seriously, though, the fact that those pics were taken from nearly identical vantage points shows a couple of things about the difference that minor adjustments can have that may be instructive to others.

                              It looks like you haven't changed anything other than the back height and back angle. If I'm correct, you have increased the back angle slightly and decreased the back height about an inch or so. While many seating therapists would freak out at the concept of doing either of those adjustments, look at how it improves the alignment of your head over your body and improves the alignment of your upper thoracic spine...



                              The added confidence you seem to exude and the notable absence of armrests certainly don't hurt.

                              Just a thought about what you would do differently for your next chair in your blog entry. You indicated that next time you would go with an 80 degree frame instead of 85. Actually, foot positioning and the knee flexion is a reason most of the ZR/ZRA's that I post here are 85 degrees with a 1" longer frame. Even though the footrest is at roughly the same location, taking the "85 deg.+1 route" to get it there may be preferable because you can still position your feet on the front of the footrest for less knee flexion, yet you still have the option of positioning them further back in tight quarters. Transfers and under seat access will also be better.

                              The only disadvantage is TiLite's upcharge for that extra inch of tubing (or charging more to use an inch less of upholstery, depending on how one looks at it). Hopefully, they will eventually relent and make the 1" longer frame a no charge option (like their competitors already do).

                              Good to "see" you.

                                SCI_OTR, you are a therapist every wheelchair user should have. Your work for your client is never done because you will check on their progress every now and then to make sure everything is all right long after they have taken delivery of the chair. That is how you have made me feel from the time when I was asking for help on the ZRA measurements till now.

                                I had wanted to post up a summary of that post in a new thread here but since you brought this up here, lets continue with the conversation which, I agree with you, could be useful to others.

                                I failed to mention one crucial point in that blog post which I should have (have to edit the blog post now). I was sitting on a Stimulite Sport in the first photo but have since swapped it with Stimulite Classic XS. With me seated higher, it appears that the back height is reduced. That 3/4" more from the Classic XS made a lot of difference to my posture, for the better, if I may add. An astute observation from you nonetheless.

                                The folding mechanism is the revised version from Tilite. It was installed as is without an adjustment to the back angle. Comparing both photos, it does appear that I am leaning more in the newer photo, and look comfortable in that position, too.

                                Taking into consideration your advice for +1.85deg for more optimal foot positioning rather than an 80 deg frame, should I add another inch to the depth if I want to install a rigid back? On the same note, should I just spec 19" seat depth (current seat depth is 17") and shorten the seat upholstery by 1" by myself later?

                                Thank you again, SCI_OTR, for your valuable insight and concern. Much appreciated.
