Harken 57mm Ratchamatic Flip-Flop Block - 2144
This Harken 57mm flip-flip block has a built in automatic ratchet which engages when your rope comes under pressure.
The flip-flop block will pivot around the rope axis to keep the line close to the deck. Hinged construction allows for various lead angles. Ratchamatic block versions roll freely in both directions under low loads and automatically engage a ratchet mechanism as loads increase, giving sailors a holding power of up to 15:1. The ratchet engagement can easily be adjusted to a higher or lower load depending on the sailor’s strength, sailing style and system usage.
Please note: This product comes with a lead time expected to be up to 10 working days.
