Mastbase Halyard Lead Blocks
Fixed Mastbase Leads
Low-profile mastbase halyard lead blocks are lightweight and can be grouped in a small 
area at the mastbase. Flared cheeks prevent chafe on the halyards. 
The high-load bearing system has a PTFE composite bushing and sideload balls. The 
sheave is hardcoat-anodized aluminum for additional strength.
Teardrop Mast Collar Blocks
These teardrop mast collar blocks coordinate well with any Harken blocks in a deck lay-
out. Sheaves feature sleeve bearings to handle high static loads and are ideal for hal-
yards. Use the blocks for direct attachment to padeyes, mast collar posts, perforated 
mast collars, or in mastbase situations where leads might change.
