I'm wondering if anyone has some advice regarding an installation problem...

I've received as a gift over the holiday's, a set of Rosen Sun Visors. Previously, I thought that sun glasses did the same thing so I wasn't going to spend money for these fancy things. But now that I've got them as a gift, I have a whole different attitude. So I found myself removing the old visor on the pilot's side and screwing in the new visor. Turns out the the only thing that got screwed was me!

I'm have trouble in screwing in the new mounting bracket. There appears to be a metal piece behing the plastic that has a smooth hole for the screw to go through before the it reaches the threaded hole in the strut. I had a problem getting the old screw out, an it was cuased by this metal strip. It was applying pressure against the old screw. That pressure was relieved when I took the old screw out and now the metal strip is preventing me from getting the new screw in. It's enough off center to get in a #8-32 screw, but the hole is for a #10-32 screw. The visors came with #8-32 screw and it was only until I found out it wouldn't tighten that I decided to check the screw sizes.

I couldn't find a drawing of what this metal strip is and before I tackle this, I'm wondering if anyone has some advice as to what this metal piece is and what it is going to take to straighten out the problem. I don't want to crossthread the screw and really mess things up. So for now, it's sun glass time when turning southwest.

Bob,

I have a 1973 C172M. I'll post the results.

I called Rosen and asked them for some suggestions. They didn't have a clue of what I was talking about. The representative said they never have seen this metal strip in all the replacements they've done. So of course I questioned what I was seeing and got a better look yesterday with a mirror and flashlight. No change to my original conclusion. Indeed I have this metal strip with drilled holes that are not cocentric with the tapped holes. In hindsight, that is why getting old screws out required an unusual amount of force not only to break it free but to unscrew it the entire length. There was only a slight amount of oxidation (corrosion) on the tip of the 3/4" - #10-32 aluminum machine screw that came out of the holes.

I'm looking for suggestions and if anyone knows what this metal strip might be.

I've thought of putting a flat tipped nail punch in the hole on one side and try to move it without messing up the threads behind the metal strip.. Haven't tried yet didn't have the punch with me. I got the impression the metal strip is not real loose. Forcing the metal strip into place on one side and putting the screw in the other has the potential for gauling the threads on the screw or internal threads. Additionally, what do I do if the second hole doesn't line up. Now I'll have one screw in and the metal stripped jamed against it.

Also what is this metal strip doing and why did it move. I wouldn't think the visour support was desiged to keep it in place.

Im not completely familiar with the Rosen visors but I did change mine to some that I purchased from Plane Plastics. I was spoiled from flying a new 172 so I wanted the tinted visor for my "71" L model. I really like them but I have had an issue with being able to fully retract them so they are out of the way. I strongly suggest that if the replacements are any different size than origional you better make sure that there is enough room for free movement. I am going to trim about 3 inches from the bottom of mine.

Not sure about your screw problem, but do know I had a tuff time getting mine tight and secure.

Good luck, and even with the troubles the new visors are a convienience that is well worth it!

Barry; what was the outcome? Did you get them to work?

Barry--did you ever figure it out? Would love to hear the final chapter. I was thinking about getting them also. Thanks.
E-mail me if possible.
