Tongue & Groove – Nickel Gap

An excellent choice for siding, tongue-and-groove nickel gap hides nails with an overlapping pattern that provides a smoother overall look. The overlapping boards in a nickel gap style hide nails and maintain a clean finish.


With standard siding, a carpenter puts one nail down through the top and one nail towards the bottom in the board’s face, so you have to putty the holes before you can apply the stain or paint the final coat. Tongue and groove solve this problem for carpenters and builders with a product they can nail blindly through the tongue rather than nailing the piece on the face.

When you install two boards together, there is a one-eighth-inch gap, roughly the size of a nickel, hence the name Nickel Gap. Nickel Gap tongue and groove can be installed horizontally, vertically, or even at an angle.
