Flannery Trim - A. Channel Screed Vent

Many of the sizes that Flannery offers of our Channel Screeds are available with Vent Slots. All Vent Slots are 1/8” wide and 1” long. They are configured at 1½” on center lengthwise and ½” on center laterally. Each row of Vent Slots lengthwise provides approximately one-square inch of vented area per lineal foot (see Vent Area Graph below).

Channel Screeds with Vent must not be installed in areas where there is solid framing, since this may block some or possibly all of the vent slots. Attach Vent Screeds to the framing with nails, screws, or other approved fastening methods. To ease installation, Flannery offers Aluminum Alignment Splices for most of its Vent Screeds. All Channel Screeds with Vent 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. Manufacturer recommends that a carbide tip blade along with lubricant be used when cutting any aluminum trims. Please specify Flannery Product Code along with the phrase "with Vent" (i.e. PCS 75-200 with Vent" or PCS 75-V-200) when ordering Channel Screed with Vent slots.
