Manufacturer's Specification

Channel Screeds are standard extruded aluminum alloy 6063 T5 and are .050 thick. Channel Screeds come in 10' lengths and shall have a standard Clear Anodized finish.

For intersections, corners, radius shapes, and channel stops see below. This product can be also be punched to create ventilation. Click on the Venting Options link in the left margin for details. 

Install all Channel Screeds on vertical surfaces using full ten-foot lengths wherever possible. Attach Channel Screeds to the framing with nails, screws, or other approved fastening methods. All screeds must be cut accurately and installed with tight, neat joints. Drywall must be inserted over the nailing flanges, and then tucked behind the 3/16" channel key. Flannery does not recommend using Channel Screeds with Alignment Splice Slots since this may inhibit the installer from inserting the drywall between the nailing flange and the plaster key. Manufacturer recommends that a carbide tip blade along with lubricant be used when cutting any aluminum trims.

This product is also known in the industry as a DCS.

For Plaster Application: Vinyl and Aluminum Connector Clips are required and will ease installation. They will align one piece of Channel Screed to another. All nailing flanges must be covered with lath and all butt joints must be sealed.

Installation Detail: Drywall Application 

Intersections and Corners

Flannery offers intersections and corners for intricate building designs that utilize intersecting lines and bands around exterior or interior walls. These junctions can be produced in the field using Alignment Splices or can be ordered from the factory as prefabricated welded units to ease installation. A seal is then applied to the back of the intersecting butt joints. Prefabricated intersections and corners are mitered and then welded at the nailing flanges. Tee and 4-way Intersections can also be ordered as notched units. All nailing flanges must be covered and all butt joints must be sealed.

Eliminating Joints

Intersecting lines can be a difficult job for even the most experienced installer. Flannery offers several solutions for reducing the time and labor involved in joining multiple lines of trim that intersect at the same point. Flannery’s Grid System gives the installer all of the vertical lines of trim with notches at specified intervals in order to install the horizontal lines of trim quickly and cleanly. Another solution for joints is Flannery’s Square Panel System. The Square Panel System is an excellent solution for large grid formations. Once the installer establishes the proper layout with one horizontal line and one vertical line, he can attach the first square on those lines allowing the rest of the squares to line up.

Channel End Cap

Flannery recommends the Channel End Cap when any channel terminates at a door or window frame. The Channel End Cap is easily slipped onto the end of the butting channel and creates an even and clean channel stop. Channel End Caps are available for any size of Flannery’s Channel Screeds.
