TW Series THRU-WALL BARRIER® Cable/Conduit Sealing Device consists of TWF frames assembled with TWB Sealing Block Assemblies. The following combinations have been classified by Underwriters Laboratories, Inc. The UL classification includes TWF6, TWF10, TWF20, TWF24 and TWF30 frames either grouted into masonry or concrete or cast into concrete installations. The inside of the frames may be coated with a silicone lubricant just prior to installation of TWB Sealing Block Assemblies. The lubricants to be used are Silipicone® Brand Release Agent made by Dow Corning Corporation or #206 All Purpose Silicone Lubricant made by Sprayon Products Division of The Sherwin-Williams Company. These will be supplied by Cooper Crouse-Hinds as TWL1 or may be obtained independently. The appropriate reducers (TWR2 or TWR3) are used in conjunction with cables having an O.D. smaller than the diameter range of the opening in the TWB Sealing Block Assemblies.

EATON Crouse-Hinds THRU-WALL BARRIER® Sealing Block Plug, Series: TW Series, Cable/Conduit Opening, 2-1/4 to 2-1/2 in Opening, 2 Openings, For Use With: TWB5027/TWB50277 Cable/Conduit Sealing Device, Wall Mounting, Malleable Iron, Electro-Galvanized

• Few parts required to seal a wide range of diameters of cables or conduits
• Easy and fast installation, using factory assembled components
• High deg of flexibility with interchangeable sealing block assemblies and a selection of different sizes of frames
• Retrofit frame allows for easy installation of frame where cables/conduit are already installed
• Cast keyways in mounting frame align and position sealing block assemblies
• Frames can be installed in wall such that sealing block assemblies can be inserted in either horizontal or vertical position
• Sealing block openings will accommodate undersize and out of round cable
• Each sealing block assembly seals multiple cables/conduits, compact design permits close nesting of cables, saving space
• Reducers permit sealing block assemblies to accept cables with smaller O.D than the specified range
• Plugs are used to fill unused openings in sealing block assemblies, blank sealing block assemblies fill unused spaces in mounting frames, providing for future expansion
• Cast stops on front pressure plate prevent sealing block assembly from slipping through mounting frame during installation
• Specially formulated elastomeric material between cast malleable iron pressure plates protects cable from mechanical damage, provides high pullout resistance and positive cable separation expands during fire to seal any voids left by burned cable insulation
• Interchangeable sealing block assemblies fit all Thru-Wall Barrier® mounting frames
• Cable/conduit sealing device is used wherever there is a need to seal cables or conduits penetrating fire or non-fire rated walls, ceilings, floors, bulkheads or decks
• Barrier also restricts water and dust and will help contain treated air
• To provide a seal for cable/conduit penetrations through masonry, concrete or steel, to restrict the entrance of contaminants through cable/conduit penetrations into clean areas
• To be used indoors or outdoors, in new construction or existing structures
