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
- Measure the wall height and subtract ½”. Measure and cut the L-Trim using aviator snips. Dry fit to ensure accuracy.
- Position the L-Trim on the end of the drywall and staple the mud flange every 6” to 10” with ½” staples.
- 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.
- 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.
- Sand lightly with 120 grit sandpaper.
Method 2: Screws or Nails
- Measure the wall height and subtract ½”. Measure and cut the L-Trim using aviator snips. Dry fit to ensure accuracy.
- 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.
- 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.
