40mm Heavy-Duty Stainless Buckle (EN ISO 12402 Certified)

This 40mm heavy-duty stainless steel buckle is engineered for demanding marine safety applications. Certified under EN ISO 12402 (the international standard for lifejacket safety) and designed to meet SOLAS requirements, it offers peace of mind in critical situations. Constructed from high-grade stainless steel, this buckle delivers superior performance where standard plastic or lightweight metal buckles might fail. It withstands extreme forces (tested beyond 326 kg) without deformation or release, ensuring that your safety equipment remains fastened under intense strain or impact.

The quick-release mechanism is intuitively designed to balance a secure lock with the ability to open rapidly in an emergency. By installing this certified buckle, you enhance the safety of your gear – a key improvement for rescue operations, maritime workers, and serious boaters who cannot compromise on safety.
