E-Flange™ Casing Bead

PVC Casing bead with Embeddable Flange design

Vinyl E-Flange Casing Bead is used to terminate stucco & stone against doors, windows and dissimilar surfaces. 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.

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.

  • 80 % more stucco embedment as compared to standard "flat" flange profiles
  • Larger triangular perforations allow more stucco mix to flow through and adhere to the substrate, improving embedment and lath/trim contact.
  • Raised flange sections allow stucco mix to flow behind the profile
  • Raised flange sections allow for more consistent and easier lath tying through flanges


Product notes:

  • Designed to terminate stucco and plaster against doors, windows and dissimilar materials.
  • Raised flange height is approximately 3/16"
  • U.S. Patent Number D842,496
