ChengFu 4 Pack Bathroom Shower Caddy Connectors Suction Cups, Heavy Strength Clear Suction Cups Compatible with Zenna Home, Simple Houseware, GeekDigg, Plumboss, Splash Home

[CRITICAL] MANDATORY WARM WATER SOAK - REQUIRED TO ACTIVATE SUCTION SHAPE Due to packaging compression, suction cups may arrive temporarily flattened. You MUST soak them in warm water for 2-3 minutes before use to restore their original concave shape. A flat cup will never create a vacuum seal. Do not skip this step. ENSURE SURFACE COMPATIBILITY - PERFORM THE 1-HOUR TEST FIRST Before attaching to your caddy, test the cup on your wall. Clean and dry a small area, firmly press the cup on, and wait 1 hour. If it falls off, your wall is incompatible. ONLY for smooth, non-porous surfaces: glass, mirror, glazed tile, polished metal, acrylic. NOT for textured tiles, grout lines, wallpaper, or painted walls. DESIGNED AS A STABILIZER - NOT A SOLE WEIGHT-BEARING MOUNT These cups are engineered to secure the side rails of hanging shower caddies against the wall to prevent swinging. They are NOT designed to be the only weight-bearing support for stand-alone, adhesive-based wire basket caddies holding heavy bottles. Please confirm your caddy type before purchase. CORRECT STEP-BY-STEP ATTACHMENT SEQUENCE Follow this order for optimal hold: ① Soak cups in warm water (Step 1). ② Clean both the cup and wall surface with rubbing alcohol and allow to air dry completely. ③ Slide the cup's opening over the caddy's side pole, position against the wall. ④ Press firmly from the center outward until all air is expelled and the cup's lip makes wrinkle-free contact. TROUBLESHOOTING & DIRECT SUPPORT If the cup won't hold, repeat the warm water soak and alcohol cleaning steps, then test on a mirror or glass to verify suction power. This helps determine if the issue is the wall surface or the cup. If problems persist, message us directly for a prompt solution - we are committed to your satisfaction.
