Flush Fire-Rated Access Panels

Larsen's has a fire-rated access panel for any wall or ceiling application. The 1" wide flange frame (L-FRAP) is standard. Stainless steel units are available in 304 with #4 finish (L-FRAPSS). For concealment, Larsen's offers drywall corner bead or plaster bead frames. These will allow finish material to be applied, leaving only the panel exposed (please contact Larsen's for sizing and availability).
