2 PRODUCT DATA SHEET Metacaulk BOX GUARD Classified under Wall Opening Protective Material as found in UL's Fire Resistance Directory January Product Description Metacaulk BOX GUARD is a one component fire rated pad for use in electrical boxes. It is inserted on the inside back wall of an electrical box, and is a highly intumescent firestop material. When exposed to fire, Metacaulk BOX GUARD will expand forming a char that will seal off the opening and prevent the spread of flames and limit the temperature rise on the unexposed surfaces. Metacaulk BOX GUARD is applied by hand, and must comply with NEC (formerly ) or other applicable codes. U.S. Patent No. 6,207,085 & 6,252,167. Metacaulk BOX GUARD Features * Easy to Install * Cost Effective * Highly Intumescent * Adheres to Back of Electrical Box * Non-Conductive * Dielectric Breakdown Voltage 22V/mil (ASTM D 149) 2. Material Properties Asbestos Fillers Solvents Hazardous Ingredients None None None Sizes (Approx.) Single box: 1 13/16" x 2 13/16" x 1/4" 47 mm X 71 mm x 6 mm Double box (two sizes) 1) 3 11/16" x 3 3/4" x 1/4" 94 mm x 95 mm x 6 mm 2) 4 3/8" x 4 3/8" x 1/4" 111 mm x 111 mm x 6 mm Color Black ASTM E 84, UL 723 Tunnel Test Flame Spread 5 Smoke Index 5 Sound Transmission Class STC Rating 55* *Tested in a UL 411 wall assembly/section to ASTM E90 3. Applications Use Metacaulk BOX GUARD on inside back panel of electrical boxes to maintain the integrity of fire rated wall assemblies restricting the passage of flames and limiting the temperature rise on the unexposed surfaces. When Metacaulk Box GUARD is used as directed, the horizontal separation between outlet boxes on opposite sides of the wall may be less than 24 inches. 4. Installation Instructions Metacaulk BOX GUARD is easy to install. Make sure rear surface is clean, dry and not contaminated. Remove protective paper from tape and stick pad to inside back wall of electrical box*. Center pad from top and bottom of box. Install switch, or outlet. Use the single pad for a single box (2" x 4"), and double pad for double box 4" x 4", and 4 3/8" x 4 3/8" pad for 4 11/16" x 4 11/16"box. Make sure installation complies with NEC (formerly ) or other applicable codes. Consult UL Directory for complete instructions and system listings. *If necessary, a maximum 3/8" hole may be created or the pad may be slit from one edge to allow easier access to the electrical box ground screw. 5. Testing Data Metacaulk BOX GUARD is classified by Underwriters Laboratories, Inc. under Wall Opening Protective Material as found in the Fire Resistance Directory.
