Spray Rib Lath

more rigid than diamond lath and helps to prevent Plaster loss

3-3/16" wide strips of plain 50lb kraft paper spot attached with glue between the herringbone mesh pattern with seven, 3/8" deep longitudinal solid steel ribs spaced at 3-7/8" intervals across the sheet.

Application(s): Stucco, Stone Veneer

Spray Rib Lath provides the superior strength and exceptional rigidity of regular 3/8" High Rib Lath while the addition of the strips of kraft paper limits the loss of plaster when used over open framing or when spray applied. Spray Rib Lath is not a replacement for Grade-D weather resistant barrier.

Spray Rib Lath is the same as 3/8” High Rib Lath with paper attached and is only available in the West Coast.
