Specifying this pattern

Name it as 4x4mm at 11.1% open. The size alone is not enough to identify a pattern: this range holds two patterns at 1.8mm, two at 2.3mm, two at 2.5mm, two at 3mm and two at 5mm, and within each pair only the open area differs.

Perforation is available plain or perforated on our panel systems. Whether this pattern can be run on a particular panel depends on the panel size and its edge detail, so confirm it with us before it goes in a specification.

Data are approximated into in/ft/gauge. See the SI unit catalog for exact measurement.
