<br />powered lighting systems include the following: EAC
<br />Prelude Main Runners: DC730112, DC730110, DC730108,
<br />and DC730106; non-powered 730106; EAC Suprafine Main
<br />Runners: DC750112, DC750110, DC750108, and

<br />DC760106; and the non-powered 760106. The EAC
<br />Prelude, EAC Silhouette, and EAC Suprafine are classified
<br />as heavy-duty in accordance with ASTM C635. See Table 2
<br />for the listed runners, and Figure 1 for a profile of these
<br />runners.
<br />The EAC main runners are cold-formed from ASTM A568
<br />steel. The runners have a hot-dipped galvanized coating
<br />and a factory-installed, polyester-painted steel cap along the
<br />entire length of the bottom flange. The EAC Silhouette
<br />series has a painted coating in addition to the hot-dipped
<br />galvanized coating and have no cap on the bottom flange.
<br />The EAC Prelude, EAC Silhouette, and EAC Suprafine
<br />main runners have a snap-on upper polymerprofile that
<br />supports two tin-plated copper conducted strips that serve
<br />to carry the low voltage current. The EAC Silhouette main
<br />runners also have a lower conductive snap-on polymer
<br />conductive strip in the lower box profile in addition to the
<br />upper conductive snap-on polymer profile. The snap-on
<br />polymer has a flame-spread index of 25 or less and a
<br />smoke-developed index of 50 or less, when tested in
<br />accordance with ASTM E84.
<br />The EAC main runners are used in conjunction with the

<br />painted steel cap along the entire length of the bottom
<br />flange. The 730145 main runners are used in conjunction
<br />with XL7325 and XL 7345 cross runners listed in Table 3 of

<br />steel cap or aluminum cap along the entire length of the
<br />bottom flange. The XL 6100 XL6500, ES7900 and XL7600
<br />and XL 76008 series have a baked polyester painted
<br />coating in addition to the hot-dipped galvanized coating, and
<br />have no capping on the lower flange. The XLAL 7200,
<br />EA7900 and EA7903 series runners are cold-formed from
<br />3003-H14 aluminum and have a baked polyester painted
<br />coating. The XL6500 series, ES7900 series, EA7900 series
