Description

The KBRC250 is the carbon version of our range of KBR blocks devoted to Racing and Super Yachts. It is a very low friction lashing block designed for larger loads. It is aboard the Ultims, Imocas, and many Super Yachts. Very few blocks on the market can display a coefficient of friction of 2% on very high loads. Titanium sheave, titanium rollers, ceramic side balls and painted carbon flanges. The KBRC is certainly the most efficient block on the market. Strengths – Used on many racing yachts & super yachts – Reliable and resistant even under very heavy load – Carbon flanges – Titanium sheave for weight and resistance – Titanium roller bearing and lateral ceramic balls on treated titanium raceways (Karver patent) – Compact tulip sheaves – Minimal friction even under very high load (2%) – Impressive longevity of the bearings (due to the low friction) – Anti-overturning shape. The pulley remains straight whatever the direction of the effort – Very generous central space to come and fix several lashings (low runners for example) – The lashing in the middle is also too big a guarantee of safety. If the pulley breaks (for external reasons of course!), The lashing will still retain the rope while the installation is secure. – A real design that stands out from other pulleys on the market – Range from 1.5 T to 40 T. We keep ALL models up to KBRC160 (16T) in stock). – Available with a leather (KBRCL) or wood (KBRCW) finish – Also available with aluminum (KBR A) or stainless steel (KBR M) flanges)
