The high load Karver blocks are assembled with self lubricating bearings (Composit fibres impregnated with Teflon) ensuring a very high working load and breaking strength in proportion to their size. These blocks are ideal for applications, where a line must not run long distance under high load (runners, barber haulers, halyards).
• Working loads are twice that of conventional roller blocks.
• Smaller size.
• Minimal weight.
• Outstanding reliability.
