Metal L-Trim #200-B (M20B)

Provides a clean finished edge for wallboard

Metal L-Trim is used to provide a clean finished edge at door and window openings or when wallboard abuts dissimilar surfaces such as suspended ceilings, beams, plaster, masonry and concrete.

Application(s): Drywall

L-Trim is installed after the gypsum panels are already in place, unlike mud-on J, which must be installed during gypsum panel installation. L-Trim is easily attached with screws or nails after the panels are in place. Installation is completed with joint compound for a smooth ready-to-paint surface.

  • Hemmed front flange for rigidity.
  • Knurled, perforated flange enhances joint compound adhesion.
  • Easy to attach and finish.

Material: 0.012 min thickness, G30 galvanized
