Back Relief Molding Knives

• Features a shallow, concave recess along the backside of the molding profile.
• Typically spans the length of the molding and varies in depth based on the profile’s overall size.
• Designed to reduce the surface area in contact with the wall or mounting surface.
• Compatible with many profile types, including baseboards, casings, crowns, and panel moldings.

• Reduces the risk of cupping and warping in solid wood moldings caused by seasonal moisture changes.
• Helps trim sit more evenly against uneven surfaces, improving fit and finish.
• Eases installation by minimizing friction and allowing for slight adjustments.
• Creates an air gap that can aid in preventing mold or mildew buildup in humid environments.

Solid Wood Moldings: Often used on baseboards, casings, crowns, and panel moldings to stabilize the profile for long-term durability.

Historic Renovations: Helps maintain the integrity of moldings in older homes with less-than-perfect wall surfaces.

Humidity-Prone Areas: Common in kitchens, bathrooms, or basements where moisture can affect the shape and fit of wood trim.

Custom Profiles: Frequently requested as an add-on feature when ordering custom molding knives to improve overall performance.
