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 layout. 
Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards. Use 
the blocks for direct attachment to padeyes, mast collar posts, perforated mast collars, or in 
mastbase situations where leads might change.
