Double sided pencil pleat, the draw cords and pockets run on both sides of the tape and these tapes pleat with the popular 'S' style pencil pleat. Reversible 'S' pleat tapes have a fully variable fullness but typically curtains need to be made with at least twice fullness to give a pleasing depth of pleat.
Six rows of cord pockets that will accept metal or plastic , for maximum stability use as many cords in the hook as possible.
Four high quality draw cords run through specially designed tubes in the tape to allow easy pleating.
