Description
The Viadana Single Ball‑Bearing Block 10 mm (model 11.80) is a compact, high‑performance block designed for small‑ to medium‑line control on sailboats, dinghies, or light‑duty rigging setups. It’s built around a smooth‑running ball‑bearing sheave to reduce friction under load — ideal for halyards, control lines, vang systems, or other deck hardware where you want efficient, low‑effort line handling.
