E-Curbs seal penetrations by using a plastic mold and a pour-in-place polymer seal. E-Curbs are designed for use on granulated modified bitumen, asphalt and coal tar B.U.R. (built up roofing), and are specified for PVC, PIB, and TPO single-ply roofing membranes. The service temperature range for the E-Curbs is -40 F to 200 F, but should not be applied at temperatures below 32 F. This rectangular E-Curb was specifically designed to work with SnapNrack one-hole standoff kits and the SnapNrack HD standoff kits. These also make good conduit penetration seals. Round E-Curbs are also available, if needed, but must be special ordered.
