Does anyone know of a roller shade of decent design that will stay on track and not shred upon use?
Presently the only inexpensive roller shade that I have been able to find is the type that is inherently flawed. First the width adjustment is accomplished by a telescoping tube that creates a dissimilar diameter. That in turn causes the blind to be biased and move to the smaller diameter side. Secondly the design of the shade also includes shade material that is intentionally weakened at vertical fault lines. That is included in the design so that one can easily tear a vertical slice off to accommodate the correct width.
When you have both diagonal roll up and a weakened material you get shredding at the smaller diameter side. The shade is worthless. It seems that self installation ease outweighs usefulness. What a joke.
The older type of roller shades were cut to length on a lathe type machine. No fault line material. No uneven diameter tube. It actually worked without shredding or shifting.
Who makes a properly designed simple inexpensive roller shade?
