12mm ISO4565 Grade 40 Calibrated Anchor Chain from Lofrans, renowned worldwide for their range of quality windlasses
Lofrans Grade 40 12mm ISO4565 is clearly stamped LFR at regular intervals as testimony to their belief in the quality of their chain
12mm ISO4565 Grade 40 Anchor Chain is generally suitable for yachts over 14 metres and up to approximately 20 metres, length overall
Displacement : Length ratio
Your cruising intentions
The anticipated anchorage conditions e.g. depth, seabed holding characteristics, the length of fetch and degree of exposure to prevailing winds
The length of chain that will be deployed and any extra scope provided by an anchor warp
The weight and design of anchor
Your anchor rode is only as strong as the weakest link so ensure that all your connectors and shackles are rated to the requisite break load
There is one main calibration for 12mm chain - ISO4565 12 x 36
It is very important to check the size and calibration of your gypsy/chain before you order
If you are unsure we can help you to decide - we will take all reasonable steps to ensure you get the correct chain
The simplest way to check that you are buying the correct calibration is to take a measurement from your existing chain, providing of course that it fits correctly.
We measure 10 links because, in practice, it is difficult to measure one link accurately enough.
The links should be laid out flat and pulled tight.
Measure from the outside edge to outside edge.
Compare your measurement with our stock:

Calibrated Chain, How Jimmy Green can help
N.B. The measurement for an old chain may be a little longer than new due to a degree of wear and elongation in use
12mm Lofrans ISO4565 pitch tolerance is Plus 0.6mm or Minus 0.3mm
Maximum Pin Diameter = 13mm = the largest pin which will fit comfortably in the end link of 12mm ISO chain
Select the largest possible galvanised shackle (or anchor connector) by pin diameter to fit the chain.
WLL = Working Load Limit
PL = Proof Load
MBL = Minimum Break Load (required)
ABL = Actual Break Load
1Kn Force = 101.972Kg Break Load
MBL 96.0Kn = approximately 9789kg
!2mm ISO4565 Calibrated chain weighs approximately 3.2kg per metre

Jimmy Green Quality Control and Accountability
Every length of chain is checked and labelled with the manufacturer, the date received and a corresponding batch number when it arrives.
The batch number is then recorded at the point of sale.
Every chain order is therefore traceable and accountable to the manufacturer Test Certificate
