I just went out to the trailer and measured the groove that the tambour fits down into and it measures 1/4" wide. According to the drawing the slats are 5/16" thick x 5/8" wide. Maybe they make 1/4" thick somewhere else in the catalog. I'll try to look and see.
You could always router the edges that go into the track to make it 1/4". I really like the look of the stainless steel. I tried to order a piece of the stainless to see if I could make it work. The Stainless doesn't come up in the shopping cart, I will have to give them a call.
That might be a possible solution, but I worry that the extra 1/16" thickness might create problems when it is retracted back into the spiral track. Guess I'll have to try and see if I can't find a 1/4" tambour. Actually I think the tambour that came in it is less than 1/4" thick. Thanks everyone for your help.
I have handled a lot of tambour over the years in my cabinet business, but this is the first that has to be waterproof.I am afraid that the metal bonded to hardboard is not going to survive direct contact with water.I believe the hardboard will slowly swell and then deteriorate.I will try to find tambour made of plastic, and if that doesn't work, I will probably reuse my existing tambour in the curved section of track, and come up with a sliding door arrangement in the section of track which is flat.Hope this makes sense to someone.Comments welcome.
