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

Lengths: All 10-foot long standard. Custom lengths upon request.
Colors: Available in white (tan/brown/gray available upon request)
Flanges: All flange widths are 1-3/4" (either side)

Product notes:

  • Designed to relieve stress and assist in controlling cracking in large areas of walls and ceilings. Specially designed connector clips are provided for alignment and base for sealants.
  • Raised flange height is approximately 3/16"
  • Factory fabricated control joint intersections are available in cross, tee and right angle configurations. Contact sales representative for more information.
  • U.S. Patent Pending   

ASTM & Code Standards

  • Vinyl Material: Complies with ASTM D1784 and ASTM C-1063, Table 1, PVC for exterior use.
  • 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
  • Assists in accomplishing ASTM C-1063, Section 7 - Tie In Control Joints through rib flange area.
  • SDS & Product Certification Information

Installation Recommendations:

  • Temporarily attach #15 Control Joints to the walls, to establish the pattern for lathing system to merge with.
  • Miter-cut all joints and set the into sealant and on the ends of joint. Clean sealant off to remain clean.
  • Run all vertical Control Joints continuous, all horizontal joints broken at those intersections only.
  • Wire-tie, or zip-tie the Control Joint flange into the lath, as outlined in ASTM C-1063. Use rib areas of E-Flange as wire access points.
Control Joint Intersections

Control Joint Intersections – Designed to relieve stress and assist in controlling cracking in large areas of walls and ceilings. Specially designed Connector Clips are provided for alignment and to provide a base for caulking. Pieces per carton are determined by product mix per order.
Caulk all intersections, butt joints, ends and corners at time of installation.

NOTE: Connector Clips are not provided with 3/8" ground. The Vinyl Corp.™ design of Control Joint Intersections provides an opening behind the connector for proper caulking. All Intersections should be embedded in caulking when applied. Custom factory-fabricated made-to-order part, parts ordered cannot be returned for credit.
