A self-furring expanded V-grooved metal lath, ideal for interior and exterior use over sheathing, masonry and other solid surfaces. The V-grooved self-furring plaster base is manufactured with evenly spaced indentations, 6" apart which run the length of the lath sheet holding the metal lath a consistent 1/4" away from the surface to be plastered. The V-groove provides an ideal point of attachment of the fastener. V-grooved metal lath is available with or without a Grade-D asphalt paper-backing, weather resistant barrier.
