E-Flange™ Casing Bead with Drip


PVC Casing Bead with embeddable flange design designed to terminate stucco and plaster with a moisture trap. ClarkDietrich E-Flange embeddable stucco profiles provide 80% more embedment than standard "flat flange" profiles.



E-Flange allows for more stucco mix to flow through the flange, providing a more thorough and consistent embedment. The unique E-Flange shape also allows for quick and easy tying of lath and other accessories. Larger, triangular perforations allow more stucco mix to flow through and adhere to the substrate, improving embedment with and lath and trims.

Casing beads should not be used in lieu of Foundation Weep Screeds at the base of the wall, as they do not meet building Code requirements.

Vinyl is impervious to corrosion when coated in veneer plaster, wet joint compounds, or when placed in contact with steel or aluminum frames and resists impacts, dents, and damage during construction. No priming is required to add paint to vinyl products due to its paint adhesion properties. Vinyl has low electrical and thermal conductivity and is considered an excellent insulator, as well as being self-extinguishing and offering better resistance to burning than many other common building materials. Additionally, vinyl has a lower cost than equivalent products manufactured from zinc or aluminum, for use when the highest levels of corrosion resistance are required.



  • Attach to substrate through E-Flange per ASTM C1063.
  • Caulk all intersections, butt joints, ends and corners at time of installation.

ASTM & Code Standards

  • Vinyl Material: Complies with ASTM D1784 and ASTM C1063, Table 1, PVC for exterior use.
  • Allows for sufficient material pressure to form full keys through the attachment flange per ASTM C926.
  • E-Flange shape provides for less surface contact with the substrate and greater contact with lath, for a more fully embedded assembly per ASTM C1861 & C1063
