Paper-Faced L-Trim (P4L)

Paper-Faced Beads & Trims

Protects and finishes wallboard edge when gypsum panels abut dissimilar surfaces


Platinum® L-Trims are used to finish the ends of wallboard where it abuts dissimilar surfaces such as suspended ceilings, beams, plaster, masonry or untrimmed door and window jambs. Tape-on L-Trims are applied in the same manner as all other tape-on beads. Joint compound is used to embed the paper-faced bead to the wallboard paper. Excess compound can be removed with a drywall knife or clean rag.

  • Virtually eliminates costly callbacks.
  • Impervious to “scuffing“ and “fluffing-up.“
  • Will not be damaged by sanding.

  • Substantially reduces joint compound consumption and eliminates one finish coat.
  • Does not require mechanical fastening (No nails, staples, screws or crimps).
  • Superior adhesion, bonding and paintability.
  • Does not require nose coating.
  • U.S. Patent Nos. 5,613,335 and 5,836,122

Material: 0.0125 galvanized coating.
