Mid-Range blocks are ideal for sheets, halyards and control lines on offshore boats because their robust construction is strong enough to handle high loads while their ball bearing sheaves reduce friction to a minimum. Their large diameter sheaves accept line to 9/16" (14 mm) and the wide range of configurations means there is a Mid-Range block that's ideal for any application.
 |
- Bearings carry high radial loads and isolate sheave from sideplates to prevent friction caused by unfair leads
- Sheave rides on ball bearings to insure lowest friction possible
- Carbon-black filled balls provide maximum UV protection

1. Unique Ratchet Sheave - The patented, eight-sided Hexaratchef sheave is machined from solid 6061-T6 aluminum for ultimate strength and corrosion resistance. It is hollow to allow large diameter with minimal weight. Sheave grips tenaciously, but allows line to be eased smoothly.

 |
2. Three-Way Head - The three-way shackle system allows swivel blocks to be locked in front or side positions using a setscrew, or left to swivel freely.
|
 |
3. Wrap-Around Head Strap - The sideplate strap wraps across the head of the block for increased strength and safety.
|
 |
4. Removable Beckets - Midrange blocks feature removable beckets to allow attachment of spliced line.
|
 |
5. Doubles and Triples Swivel - Double and triple Midrange blocks feature swivel posts. Blocks can be locked in front or side shackle positions or left to swivel freely.
|
 |
6. Reversible Cams - Cams on Midrange fiddles and single ratchets can be reversed so blocks may be set for up or down release.
