Single Block 16mm Swivel | Master Dinghy
Dinghy is Masters' smallest product series of ball-bearing blocks, perfect for control lines on dinghies and smaller sailboats. The sheave is 16 mm with steel ball bearings, which provides low friction and smooth rotation. The side plate is made of acid-proof stainless steel A4/316 for high weather resistance and maximum strength.
APPLICATION AREAS

- Mainsail systems, headsails, and spinnakers
- Halyards, vangs, and backstays
- Control lines for boats of all sizes

FREQUENTLY ASKED QUESTIONS (FAQ)
Which line diameter fits the block?
The block has a 16 mm sheave and fits lines up to 6 mm in diameter.
What is the difference between working load and breaking load?
The working load is the load the block is intended to be used with continuously. The breaking load is the load at which the block will fail and should never be used as a design value.
Does the block need maintenance?
The ball bearings normally do not require lubrication. It is recommended to rinse the block with fresh water after use in salt water so that salt and dirt do not accumulate in the bearings.
