6mm 1/4" chain marking kit
Everything you need to mark a chain properly, in one box — including the guide plate that tells the helm what the colours mean.
Chain bigger than 12mm? Those are custom made to your chain — find your size here.
What's in the box

Your guide plate
This is what you'd mount at the helm.
The plate updates as you configure the kit — one row per marked position, in the sequence we recommend. Build it yourself in about thirty seconds: cut the number tabs from the rack, press them flush into one column, slot the matching colour tabs opposite.
- Colours and numbers are moulded into the face — they can't wear off.
- One plate is included free with every kit. Spares from £4.58 — one for the helm, one for the bow.
- Want the boat's name on it? Custom plates from £25.44 in A7, A6 or A5.
Fitting
Three movements per marker. One screwdriver.
No degreasing, no masking, no drying time. You can mark the whole chain on the pontoon between trips.
Snap two halves off the rack
Break off the two opposite halves and place one either side of the link. One half has a spigot, the other a socket and screw hole.
Press together until aligned
Firm pressure closes the marker around the link. It grips the link itself rather than wedging into the gap — which is why it doesn't pop back out.
Drive the stainless screw home
One 316 stainless screw, snug but not over-tightened. If you want to move it next season, unscrew it and relocate.

Still deciding?
Get it wrong and we'll sort it out.
Order the wrong size and we'll exchange it. That isn't marketing copy — it's what our customers say happened.
Ordered the right markers but the wrong size. My fault. Immediate reaction and free exchange and also a refund from Anchoright. Impossible to get better service anywhere in the industry.
Excellent! Ordered online on a Sunday and arrived on Tuesday! Really good product. Super easy to attach to the chain and run seamlessly through windlass. Markers feel robust so hopefully they'll last well.
