K-Block range with balls and rollers:
The standard Karver blocks are assembled with rollers and balls bearing ensuring a very low friction. These blocks are ideal for applications, where a line under high load must run for a long distance (sheets, halyards....)
High working load block range:
The high load Karver blocks are assembled with self lubricating bearings (Composite fibers 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. (E.g. runners, barber haulers, halyards).
Advantages:
Working loads are twice that of conventional roller blocks
Smaller size
Minimal weight
Outstanding reliability
