Abstract: A batten for securing sheeting to a substrate is comprised of a lengthwise strip having fastening surfaces thereon. The fastening surfaces are spacially related along the length of the strip to coincide with the spacial relationship present between structural members of a standard wall structure. The fastening surfaces thus serve as indicators of the locations of such structural members. Each fastening surface includes a moisture barrier that forms a moisture-tight seal around a fastener when driven through the fastening surface and sheeting and into the substrate.
