Description
The Ronstan 50 mm Series 50 Double Block with Becket and Universal Swivel Head (RF51210) is a great all around solution. Self-lubricating Acetal polymer sheaves running on polished stainless steel races perform equally well with dynamic loads and high static loads. For durability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing. Head can be locked at 0° or 90° by engaging the grub screw in either the 0 or 90 degree position.
