- Few parts required to seal a wide range of diameters of cables or conduits
- Easy and fast installation, using factory assembled components
- High degree of flexibility with interchangeable sealing block assemblies and a selection of different sizes of frames
- 1-piece cast malleable iron or steel mounting frame can be cast into concrete during wall construction, grouted in masonry surfaces, or welded into steel bulkheads at any time
- 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
- Specially formulated elastomeric material between cast malleable iron pressure plates protects cable from mechanical damage
- Provides high pull-out 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
