Abstract: A curtain track assembly comprising a telescopic track apparatus (12) with waterproof pressure-sensitive adhesive pads (18), a shower curtain and or liner cartridge with a unique fold pattern and a permanently attached curtain carriers (20) and or curtain clips (24). The telescopic track apparatus (12) consists of two parts, one half being of a larger inner dimension than the other, so that the smaller half of the track (14A) is smoothly fitted into the larger part of the track (14B). The track parts (14A and 14B) have an open seam shaft or c-channel (30) running lengthwise along the bottom to allow the curtain carriers (22) and curtain clips (24) to slide smoothly along the track parts (14A and 14B). The track parts (14A and 14B) are open at either end (50) allowing for insertion of the curtain liner cartridge (20), curtain clips (24) and end caps (26).
