Teardrop blocks are ideal for use as mastbase leads and for other applications where limited articulation or direct attachment is desired. When attached to an appropriate padeye, Teardrop blocks will not hit the deck when lines are slack, yet allow sufficient movement to ensure fair leads when jumping halyards. They are often used on permanent backstays of fractionally rigged boats where the backstay can be spliced directly to the head of the block.

The 3042 and 3046 are low-load blocks designed for use on production boats that have mounting posts on the mastcollar.
