Install all Plaster Channel Screeds using full ten-foot lengths wherever possible. Attach Channel Screeds over the weather resistant barrier to the framing with nails, screws, or other approved fastening methods. All Channel Screeds 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. To assist the installer, Flannery provides vinyl connector clips with every stick of Channel Screed ordered. Manufacturer recommends that a carbide tip blade along with lubricant be used when cutting any aluminum trims.


Many of Flannery’s Plaster Channel Screeds come with Aluminum Alignment Splices to ease the installation process and create crisp and clean butt joints and lines. To assist the installer, Flannery also provides vinyl connector clips with most Channel Screed sizes.


Flannery offers Channel End Caps for all sizes of the Plaster Channel Screed series. End Caps create a termination point for any Channel Screed where the channel may terminate against a dissimilar material such as a door or window frame. Channel End Caps can also be used when a channel terminates in the middle of a plaster wall.


The Beveled End Enclosure is a product that was designed to allow any Plaster Channel Screed to terminate properly at stucco corners. The unique angle and plaster key of the Beveled End Enclosure is ideal for separating the channel from the stucco layer particularly when a corner has welded wire corners installed. The Beveled End Enclosure is available for any size of Flannery’s Plaster Channel Screeds. Flannery can factory weld them to specific lengths of channel or provide them separately.



Flannery offers prefabricated intersections and corners for intricate building designs that utilize intersecting lines and bands on exterior walls. 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 Plaster Channel Screeds 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 Order form below to place an order or receive a quote.
