Plastic Trim

Select this plastic trim for its chemical resistance. Often used on panels, boards, signs, and mirrors, it protects edges from impact.

Very flexible trim is flexible enough to bend around tight corners.

Trim with a hard or medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.

Adhesive-back trim allows for easy installation.
