⚠️ Sizing & DIY Modification Guide (Crucial!)

Please review these specific requirements for Atradesen.com customers before placing your order:

• Max Glass Thickness: Safely clamps glass/acrylic up to 15mm thick using premium silicone gaskets.
• 🚨 Thin Plastic Tank DIY: If installing on a very thin plastic reservoir, the threaded pipe may be too long to clamp tightly. You can easily saw/cut the thread shorter manually to achieve a perfect seal.
• 20mm Models: Fits 20mm O.D. Hard Pipe | Drill Hole Required: 20-22mm
• 25mm Models: Fits 25mm O.D. Hard Pipe | Drill Hole Required: 26-28mm
