Lewmar 72mm HTX Fiddle Block with Becket – Black | 29197234

Lewmar 72mm HTX Fiddle Block with Becket – Black | 29197234

The Lewmar HTX 72mm Fiddle Block with Becket combines high-load capacity with the versatility of a built-in line termination point. The fiddle configuration delivers compact mechanical advantage in a slim profile, while the integrated becket allows the standing end of the purchase line to terminate directly at the block — making it the right choice for multi-part purchase systems, cascades, and fine-tune controls where a standard fiddle block won’t do.

The self-aligning swivel head adjusts to changing lead angles automatically, reducing friction and side loading across the full range of motion. Strong aluminum side cheeks, a central plain bearing, and Delrin side-thrust ball bearings complete the HTX construction.

Fitment Note

Important line-size detail: While the broader 72mm HTX family is rated for line up to 14 mm (9/16"), Lewmar’s fiddle-specific guidance indicates a maximum of approximately 12 mm (1/2") for this configuration. If you’re running 14 mm line, confirm the exact rope clearance for this fiddle variant before ordering.

Parts Desk Insights

Best use case: This block is the right choice when you need a high-load fiddle block and a built-in termination point for the standing end of your purchase system — the becket eliminates the need for a separate attachment shackle or bail at the base of the tackle, which keeps the system more compact and reduces the number of potential failure points. It’s particularly well suited to vang and backstay purchase systems on performance cruisers and racers where space is tight and loads are high.

The key distinction from the standard 72mm HTX Fiddle is simply the becket — if your purchase system doesn’t need a standing-end termination at the block, the version without becket is the simpler choice. And as with all HTX fiddle variants, confirm your rope diameter against the 12 mm fiddle-specific limit before ordering if you’re running larger line.
