samples of walnut displaying light and moderate cross bar

Cross Bar

What is cross bar? Cross bar is a visible irregularity in the grain resembling a dip that typically runs at an angle across the grain. Sometimes referred to as "Tiger Stripe." TruStile allows light to moderate amounts of cross bar across the face of a door.

Walnut sample showing pin knots

Pin Knots

Pin knots are the result from the growth of small branches that measure generally ¼” or less in diameter and will typically have a darker, solid center. You can expect to see pin knots randomly dispersed across the face of a trustile door.

Detail of walnut wood showing conspicuous burl

Conspicuous Burl

A conspicuous burl is an area where the wood grain twists and swirls. This usually appears near where branches grew from the tree. This characteristic stands out because of noticeable color changes or clusters of small dark spots in the wood. You can expect to see conspicuous burls randomly dispersed across the face of a trustile door.

UV Sensitivity

Walnut is susceptible to fading from prolonged exposure to UV light. Though TruStile factory finishes include UV blockers, we recommend choosing a darker finish for doors that will receive direct sunlight.
