This is our smallest fiddle block, created by merging a 225 Micro becket block for the larger sheave with a 16 mm single block. Accepts 5 mm line. The Micro has Delrin® ball bearings and the 16 mm has stainless steel bearings.
Low-friction Micro blocks are compact and lightweight. They are ideal for sailboards, smaller dinghies, and lightly loaded control lines on boats of all sizes.
Micro block sheaves run exclusively on ball-bearing systems for fast trim and release under any load.
