SHAAMA's shower seal set includes an acrylic threshold and seal strip, perfect for 3/8-inch (10mm) frameless glass doors, 36 inches each. Made of clear, sturdy acrylic, it resists discoloration and lasts years. The strip pairs with the threshold to seal gaps, preventing leaks and keeping the floor dry—no splicing or micro gaps. Its soft fins ensure smooth door movement, while absorbing shocks and blocking dust. Installation is quick: no adhesive, just snap into place. Note: Tear off the red backing first. Ideal for a dry, hassle-free shower.
