A word about Quality at Colligo Marine

 

Our Goal at Colligo Marine is to bring to market the highest quality product.

We strongly believe that "Quality Sells Itself" and that is our Mantra.

 

About our Safe Working Load (SWL)

We pull test a statistical sample of all of our products, manufactured or

purchased components.  The SWL is determined by us by the mechanical

pull testing that we have completed by an independent lab.

 

Shackles

Our shackles are purchased from an outside supplier and we pull test a statistical

sample from every lot received, every time.

Swivels

Our Swivels are purchased from an outside supplier and we pull test a statistical

sample from every lot received, every time.

Bridle Plates

Our Bridle Plates are engineered and manufactured by us and a statistical sample

of every lot is pull tested for strength to ensure they meet our quality standards.

 

We use a factor of safety of 4 to determine our safe working load limit.  The actual,

statistically determined, ultimate tensile strength of each part is 4 times the Safe

Working Load.
