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.

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.
  • This product has sharp edges and may cause cuts. Wear leather work gloves when handling.

Material: 0.012 min thickness, G30 galvanized

INSTALLATION

This product has sharp edges and may cause cuts. Wear leather work gloves when handling.

Metal L-Trim can be installed using a variety of methods.

Method 1: Staples

  1. Measure the wall height and subtract ½”. Measure and cut the L-Trim using aviator snips. Dry fit to ensure accuracy.
  2. Position the L-Trim on the end of the drywall and staple the mud flange every 6” to 10” with ½” staples.
  3. Using an 8” taping knife, apply the first coat of joint compound to the surface of the L-Trim. The use of lightweight or setting-type compound in this step will reduce shrinkage and speed up drying time. Let this dry completely, for several hours or overnight.
  4. Using an 8” or 10” taping knife, apply a light finish coat of joint compound. Feather the compound beyond the previous coat.   The use of all-purpose or topping compound will make for a more durable finish. Let this dry completely, for several hours or overnight.
  5. Sand lightly with 120 grit sandpaper.

 Method 2:  Screws or Nails

  1. Measure the wall height and subtract ½”. Measure and cut the L-Trim using aviator snips. Dry fit to ensure accuracy.
  2. Position the L-Trim on the end of the drywall and fasten the L-Trim with screws or nails using the smaller nail holes on each mud flange.
  3. Using an 8” taping knife, apply the first coat of joint compound to the surface of the L-Trim. The use of lightweight or setting-type compound in this step will reduce shrinkage and speed up drying time. Let this dry completely, for several hours or overnight.
  4. Using an 8” or 10” taping knife, apply a light finish coat of joint compound. Feather the compound beyond the previous coat.   The use of all-purpose or topping compound will make for a more durable finish. Let this dry completely, for several hours or overnight.
  5. Sand lightly with 120 grit sandpaper.
