Ronstan Batten receptacle link

Fast, simple and reliable. The patented Ronstan Ballslidetm system uses the existing cleat in the mast. It is therefore not necessary to install a rail. The Ballslidetm carriages have so-called "captive ball bearings", which means that the balls remain in the carriage, even if the carriage is not mounted, and can therefore be easily removed and placed on the mast when the mainsail is to be mounted.
