One block, every job

01

Hang it and go

On its own, hanging from the included stainless omega shackle: a turning block ready in seconds, wherever you need it. No kit required.

02

Opens on a loaded line

No need to unreeve the sheet: open the body, drop the line in, close it. Even with the rig in place.

03

The Conversion Kit

The box that multiplies the block. Inside is everything you need:

4× long bolts M6: 45, 50, 75, 80 mm
2× self-locking nut M6

04

Flat on deck

With the kit you bolt the block flat on deck, low profile: halyard and sheet leads where a dedicated block used to go.

05

Double: 2:1 tackle

Two identical bodies joined by the kit: a 2:1 tackle for the vang, traveller or barber hauler, using the line you already have.

06

Triple: maximum purchase

FAQ

Can one block really do so many jobs?

Yes. A single Olli Flex covers turning blocks, tackles, quick rigs and temporary installs — 6+ applications. It replaces a drawer of single-purpose fittings.

How do I turn one block into a double or triple?

Add the matching Conversion Kit (sold separately, one per size and load class). It joins identical Olli Flex blocks into double and triple configurations with a few common hand tools.

What’s the difference between Standard and High Load (HL)?

HL versions use a 6061-T6 aluminium sheave instead of POM and a larger shackle, raising the working load on the same line diameter (e.g. 900 to 1,700 kg on Ø50).

Which size do I need?

Ø50 (M) takes up to 12 mm line, Ø60 (L) up to 14 mm. Match the size to your line and the working load to your application.

Does it need maintenance?

Very little. The self-lubricating sheave runs without metal bearings, so there is nothing to seize or corrode — just rinse with fresh water after use.

What makes it “openable”?

The interlocking aluminium bodies rotate against each other, so you can open the block onto a line already under load — handy, but the real advantage is reconfiguring one block into many setups.
