Specs, MSDS, and LEED Information for Flannery Trims & Products
Flannery’s Plaster Control Joint (PCS 75-25-25) is a wall trim that creates a ¼” aesthetic horizontal or vertical reveal in a typical stucco or plaster wall system. This part breaks up a plaster or stucco wall by creating horizontal and vertical reveal lines. Flannery’s Plaster Control Joint is available with Aluminum Alignment Splices to ease the installation process and create crisp and clean butt joints and lines. Plaster Control Joints are installed much like Plaster Channel Screeds but have a small ¼” depth that the Plaster Channel Screed cannot achieve. Flannery’s Plaster Control Joints can also be custom fabricated to be corners, intersections and radius and will be considered a custom part.

Install all Plaster Control Joints using full ten-foot lengths wherever possible. Attach the Control Joint to the framing with nails, screws, or other approved fastening methods. All Control Joints must be cut accurately and installed with tight, neat joints. All nailing flanges must be covered with lath and all butt joints must be sealed. The Manufacturer recommends that a carbide tip blade along with lubricant should be used when cutting any aluminum trims.
Channel Alignment Splices
Flannery’s Plaster Control Joint comes with Aluminum Alignment Splices to ease the installation process much like many of our other reveals. The alignment splices can also help to create crisp and clean butt joints and lines. If you need more splices then the ones provided for your project, just ask! To assist the installer, Flannery also provides vinyl connector clips with most Channel Screed sizes.
Flannery offers prefabricated intersections and corners for intricate building designs that utilize intersecting lines and bands on exterior walls. Intersections and corners are a great option to make the trim stand out more if you want an accent or focal point in your building design. Prefabricated intersections and corners are mitered and then welded together at their attachment flanges, then vinyl tape is applied to the back of the reveal to prevent water intrusion. Factory welded intersections and corners come with 6” legs, however custom leg lengths can be ordered.
Flannery can radius Control Joints when the trim runs along a “curved” or “radiused” plane. Radiused material is bent to a project’s dimensional requirements and is considered a custom product. Download the Radius Form or view all of our radius forms.
