Anyone know where I can get a replacement zipper for my sleeper curtains?

The T660 we have on our fleet has the zipper broken too. Guess it's a common fail point.

 

Maybe attach some button fasteners or velcro straps.

 

If you can take the curtains out I would think an upholstery shop could replace the zipper for you.

 

I've found that the brass or metal zippers hold up a lot better than the plastic replacements.
I saw on the site they also carry those in the heavy duty and extra long lengths. Not sure about 2-way style.

 

Yes, Velcro that simply sticks on one side.
Or magnets.

Velcro strips can be found at any truck stop.

 

The only KW Aerocab I've ever driven didn't have enough curtain to overlap and Velcro. It was such a pain I started draping a blanket over the seats when I went to bed.

 

Sometimes if a tailoring shop is closer, they can do this as well. They do have machines to sew thru all types of fabric, and the cost may be nearly the same. In fact I had a tailoring shop get me a long zipper as well , just not for a sleeper curtain set.
