Technical Breakdown
- Top Block Measurement: The digital caliper shows a sheave diameter or cheek width of 42.48 mm (roughly 1-11/16 inches). This corresponds to a compact marine block typically used on small day-sailers or control lines (such as vangs, outhauls, or traveler systems) on larger yachts.
- Component Connection: Instead of a factory-built "fiddle block" where two sheaves share a single continuous side plate, this setup joins two independent swivel blocks via an intermediate mechanical swivel link.
Assembly Purpose
Linking two blocks like this allows lines running from different angles to change direction independently without twisting or binding the hardware. It is often used to form temporary block-and-tackle systems or specialized rigging leads.
