Product details

Excellent quality! 3-sheave block with ring. The side panels are made of high-quality Hostaform C, seawater-resistant and shape-retaining. The fittings, bolts and rivets are made of stainless-steel materials.

Their balanced price-performance ratio is unmatched, with their products repeatedly winning awards in sailing and yacht magazines.



Cleaning and Maintenance of Blocks:

  • Rinse blocks regularly and thoroughly with warm fresh water to remove salt and dirt (carefully assist with a soft brush if necessary).
  • For heavier soiling: Soak the block in warm fresh water with a little dish soap and move the rollers (do not use harsh cleaners).
  • Avoid pressure washers, as water and dirt can be forced into the bearing.
  • Allow to dry thoroughly afterwards to prevent corrosion.
  • Lubricate only when necessary and according to the manufacturer's instructions.
    • Note: Many modern bearings are maintenance-free or self-lubricating – improper lubrication can impair their function.
  • Disassemble only if explicitly instructed by the manufacturer, as not all blocks are designed for maintenance or disassembly.

sprenger delivers a very good price / performance ratio with a high quality standard - you can always buy blind and SVB delivers fast and reliable - great.

Very smooth, stable block. One point deduction for the price, which is too high for all products in the sail area.
