Why do some roller screening tools have 2+ inch rollers and others have 1 inch, which
type makes do you recommend and why? Thanks,

Thank you for your patience. The 2" wheel is the convex type used for basic replacement of screen wire in a screen frame. The 1" concave wheel is used to install a wider screen spline or installing "glass" glazing vinyl. You may also use the 75-019 rolling tool which also includes both a convex and concave wheel.
