AquaKnight: Tested Stainless Steel Clamping for Membrane Drains

Your reputation hinges on specifying drainage solutions that perform flawlessly. Aquaknight’s membrane clamping range, featuring stainless steel clamp rings, delivers unmatched clamping force for all membrane types 0-12mm thick, ensuring a watertight seal. Unlike plastic clamp rings which lack rigidity, Aquaknight's stainless-steel clamps provide ten times the strength, as verified by WSP Laboratories’ deflection tests. This eliminates reputational risk tied to leaks or system failures.

Check out the Aquaknight Industries WSP deflection test:
