The System 30 Performance Fiddle sheave End Control is designed for a low profile - high performance jib/genoa trim with 6:1 purchase. It features ø50 mm and ø30 mm machined aluminium sheaves with Torlon ball bearings separated from each other in ball cages. This prevents ball-to-ball contact and makes for low friction. The fitting is anodized aluminium with a shock absorbing rubber buffer. The hole in the base is a termination (becket) for a control line. 

Ideal dimension of the control line is ø7 mm. See Seldén's line packages.
