Restringing instructions for day/night shades. When I did mine, I first bought a set of
darning needles from the local JoAnn Fabrics. One of the needles was the right size for the holes in the bars and pleats. The needle allowed me to thread the string through all of the pleats in a section at one time, making restringing an easy job.
We have two day/night shades in our MH and in the past 11 years I have restrung one shade twice and the other once. The three metal rails in the shades have nylon grommets in the holes so that the strings slide through the holes on a smooth slippery surface. The first time I restrung both shades I found that the grommets had been inserted from the wrong side, which allowed the strings to rub against the sharp edge of the metal hole. This frayed the strings, resulting in an early failure. The second time I had to restring a shade was due to one of the grommets coming out of the hole in the rail, again resulting in the string fraying against the sharp edge of the hole.
One last caution - don't over tighten the strings when you hang the shades. The strings should be just tight enough so that they don't come down when going down the road.
