Install all T-Molds using full ten-foot lengths wherever possible. All Aluminum Trims must be cut accurately and installed with tight, neat joints. Manufacturer recommends that a carbide tip blade along with lubricant be used when cutting any aluminum trims.

If used in a stucco wall system, attach all Termination Trims over the weather resistant barrier (WRB) to the framing with nails, screws, or other approved fastening methods. A shiplap of building paper or WRB may need to be installed over the attachment flange if the trims are being used as a stucco stop. All nailing flanges must be covered with lath and all butt joints must be sealed.

Flannery offers prefabricated corners for intricate building designs that utilize intersecting lines and bands on exterior walls. Prefabricated 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 corners come with 6” legs, however custom leg lengths can be ordered.
