These are incredibly handy for plaster repair. You can draw a sagging ceiling or wall plaster into place and fully support it. Using a drywall screw, draw the plaster tight to the lath backing; the washer flattens as it is squeezed by the screw.

Perforations give tooth to a covering plaster coat. Instructions included. Zinc-plated washers are 1" in diameter and require #6 × 1 5/8" drywall screws (not included).

Made in USA.
