Description

Flexible Fit for Trim and Moldings

This back relief profile knife is designed to make your trim installation smoother and more forgiving. By creating a small channel on the back of your molding stock, this profile helps your pieces lay flush against uneven surfaces—ideal for older homes or less-than-perfect walls.

Purpose

• Reduces surface contact to allow moldings to flex and adapt to curved or wavy walls
• Creates a recessed back that improves adhesion and stability during installation
• Helps ensure seamless trim lines even on rough or unlevel walls
• Ideal for achieving a snug, gap-free appearance in professional finish work

Common Usage

• Baseboards: Helps moldings sit flat against irregular walls or subfloors
• Window & Door Casings: Ensures tight joints and easier alignment during trim work
• Chair Rails: Useful for wrapping uneven wall sections or around corners
• Crown Molding: Occasionally used where walls or ceilings aren’t square, adding helpful flexibility
