Strop Lock

Southern Spars’ Strop Lock (patent pending) is the first of its kind. The only solution capable of handling the loads required to keep constant tension in the luff of sails such as asymmetrical spinnakers and code zeros while always aligning perfectly to the direction of the load. Benefits of the Strop Lock

• The Strop Lock is an external locking system designed to be easily retrofitted to existing masts.   Its simple construction means it can be easily maintained, serviced and removed.

 • Made from titanium and aluminium, it is an alternative to an internal lock system and reduces weight associated with internal structural reinforcement.

 • Engineered to minimise compression on the mast, the Strop Lock relieves stress by concentrating loads in the direction that they are applied.

 • Proven for its performance and reliability, the Strop Lock has been put through rigorous testing on some of the world’s best racing yachts including 2005/06 Volvo Ocean Race winner ABN AMRO ONE, 2005 Rolex Transatlantic Challenge winner Maximus and 2005 and 2006 Sydney to Hobart Race winner Wild Oats XI.

With a range of safe working loads from 2,000 to 15,000 kgs, the Strop Lock comes in six sizes: 2, 4, 6, 8, 12 and 15 tonne.

Southern Spars’ Strop Lock was awarded Special Mention at the 2005 METS DAME Awards
