You get all these components with full installation instructions when you buy a Tradux Wall & Liner Transition Piece.
Each kit contains all the parts necessary to pass either a flexible hose (3/4", 1", 1 1/4", 1 1/2" or 2" bore) or a cable (up to 9mm outside diameter) through a pond wall or flexible liner. Take a look at our Accessories section for flexible hoses, hose clips and other useful parts.
