Olli™ · Anti-Shock Snatch Block

The block that opens where you need it

The promise

Block + low friction ring in one tool: total control in every maneuver

01

Openable

A rotational (not hinged) opening: it rigs even on loaded lines, and the mechanism stays completely unstressed under load.

02

Anti-shock, anti-scratch

The technopolymer shells protect both boat and block: if it drops or hits the deck, no marks, no noise.

03

Self-lubricating

No bearings: the self-lubricating sheave in a sealed body removes rotational friction. Zero maintenance, forever.

FAQ

Common questions

Does it oxidize over time?
No, it doesn't. Olli™ Block contains no materials subject to oxidation.
Does it have bearings inside?
No, it doesn't use bearings. Its self-lubricating technology eliminates the rotational friction of the sheave.
Is the Dyneema® loop included?
Absolutely yes. With the snatch block you'll also receive its Dyneema® loop, already prepared and ready to rig.
Since it's openable, can it break under load?
No. Olli™ Block is a monolithic design with no tension applied to the opening mechanism: the system is rotational, not hinged, and stays completely unstressed under load.
Where can I use it on my boat?
Anywhere you'd use a traditional block, with a Dyneema® loop instead of a stainless shackle: no pins that unscrew. Avoid sharp edges that could damage the loop, or protect it with a soft sleeve.
