Quick Overview

U-Trim, or Spackle J is used to provide maximum protection and clean finished edges on gypsum panels around door and window openings and when wallboard abuts dissimilar surfaces, such as suspended ceilings, beams, plaster, masonry and concrete. U-Trim is easily installed by sliding trim over the edge of the board and nailing or screwing through the knurled (long) flange. Installation is completed with application of joint compound for a smooth ready-to-paint surface.
