For your
32-020: Is the thickness for the staple strip or the glide area?
For your
32-011: Combining the base and roller, how much of an offset will this create?
For your
32-011,
32-020, and
32-114: Are any of these available in black?
Do you have matching "buttons" or "strips" that would mount on the bottom of the side to reduce friction at the drawer's back?
Thank you for any information or suggestions that you can provide.
