2" Counter Board - Counter Flashing for Siding Clearance - 100 Pieces

Tamlyn 2TF Counter Flashing — Patented Clearance Solution for Siding and Solid Surfaces - 2" x 1" x 2" x 7/8" x 8' - 2TF The Tamlyn 2TF is a patented counter flashing profile engineered to provide reliable clearance between siding products and roofs, decks, paths, steps, driveways, or any other solid surface. Designed for professional installers working with exterior cladding systems, it prevents moisture intrusion and physical contact at critical transition points. Available in two material options — primed galvanized steel and color-matched aluminum — the 2TF integrates cleanly into a wide range of residential and commercial siding assemblies. Standard length is 8 feet, with all dimensions nominal. Unlike generic field-bent flashing, the 2TF is a purpose-built, patented profile that maintains consistent geometry across every piece, eliminating on-site fabrication variability. The color-matched aluminum variant ships pre-coated in popular siding and soffit colors, reducing touch-up labor and delivering a finished appearance without additional painting. The primed galvanized steel option accepts field-applied paint for custom color matching on any project. Key Features & Benefits Patented Counter Flashing Profile The 2TF geometry is a protected, purpose-engineered design — not a commodity angle. Contractors get a consistent, code-compliant profile every time, which reduces installation errors and callbacks related to improper clearance at siding terminations. Primed Galvanized Steel Option The primed variant is manufactured from .019″ ± .003 galvanized steel with a proprietary coating that resists harsh weather conditions and promotes paint adhesion. This makes it suitable for projects where field-painting or custom color matching is required without sacrificing corrosion resistance. Color-Matched Aluminum Option The color-matched variant is fabricated from .019 ± .003 aluminum sheet, coated on both sides with a paint system specifically formulated for exterior exposure. Available in most popular siding and soffit colors, this option eliminates the need for field painting and delivers a polished, integrated appearance at the flashing line. Dual-Side Paint System on Aluminum The aluminum version is coated on both sides, not just the exposed face. This matters because moisture can contact the back of the flashing during installation and in service — a single-side coating leaves the concealed face vulnerable to oxidation and paint failure over time. Consistent 8-Foot Standard Length The 8-foot standard length aligns with typical stud spacing and panel module dimensions, reducing cut waste on most residential and light commercial projects. Consistent lengths also simplify ordering, staging, and inventory management across multi-unit jobs. Compatible with Multiple Siding and Soffit Systems Because the color-matched option is available in most popular siding and soffit colors, the 2TF can be specified across a broad range of exterior cladding systems without requiring custom orders or special paint processes. This streamlines procurement for contractors managing multiple product lines on a single job. Common Applications Siding-to-Roof Transitions The 2TF creates the required clearance gap where siding panels terminate above a roof surface, preventing direct contact that would otherwise trap moisture and accelerate rot or corrosion at the base of the wall assembly. Siding-to-Deck Transitions Where exterior siding runs down to a deck surface, the 2TF provides a clean, weather-resistant termination that maintains the necessary standoff distance to prevent wicking and moisture damage at the siding base. Siding-to-Driveway or Path Transitions At grade-level transitions against concrete, asphalt, or paver surfaces, the 2TF protects the siding termination from ground moisture, splash-back, and physical contact with hard surfaces. Siding-to-Step Transitions Steps and stair landings create complex intersection geometry where siding must terminate cleanly. The 2TF provides a consistent flashing detail that handles these transitions without custom fabrication. General Solid Surface Clearance Any application where a siding product meets a solid horizontal or near-horizontal surface benefits from the 2TF profile, providing a standardized, patented solution rather than a field-improvised detail.

Tamlyn & Sons, Inc.) Frequently Asked Questions Q: What is the difference between the 2TF and CF4 variants? A: The 2TF designation typically refers to the primed galvanized steel version, while CF4 refers to the color-matched aluminum version. The primed steel is intended for field painting; the aluminum is factory-coated on both sides in popular siding and soffit colors. Q: Can the primed galvanized steel version be painted in the field? A: Yes. The proprietary coating on the primed version is specifically formulated to promote paint adhesion, making it suitable for field-applied topcoats to match any project color requirement. Q: What clearance does the 2TF provide between siding and a solid surface? A: The profile dimensions are nominal and shown in the catalog page. Refer to the PDF catalog for exact leg dimensions and profile geometry to confirm clearance for your specific application. Q: Is the 2TF suitable for use with fiber cement siding? A: Yes. The 2TF is compatible with fiber cement, vinyl, engineered wood, and other common exterior siding products wherever a clearance flashing is required at the base of the wall or at surface transitions. Q: How many pieces are required per order, and what is the standard pack quantity? A: Standard length is 8 feet per piece. Pack quantity and minimum order information should be confirmed with DTS at time of purchase, as this may vary by color and material option. Q: Are color-matched options available for all siding brands? A: The color-matched aluminum version is available in most popular siding and soffit colors. For a specific color match to a particular manufacturer's palette, contact Tamlyn or your DTS sales representative to confirm availability before ordering.
