SP Assemblies
With decades of experience to our name here at Ibex Marina Ropes, our SP Assemblies are precision-built to British Standard BS3SP 170-171. This standard covers both heavy duty (BS3F70) and light duty (BS3F71) shock cords, with diameters ranging from 3mm to 16mm. All this means you can rely on them to provide peace of mind for high-risk, high-spec applications.
Originally intended for aerospace use, today they are also used in a wide range of industries for restraining purposes.
The stainless steel end fittings conform to BS3SP 168-169.


Every component is built to spec — from the core shock cord to the stainless steel end fittings — ensuring full compliance and repeatable performance. That means you can trust our assemblies for endurance and reliability, whether you are securing sensitive equipment, managing dynamic loads or working in corrosive environments.
In short, if you need certified strength and total consistency, our SP Assemblies deliver.
