Used on a multitude of boats & regarded by many as the best auto-ratchet block available.

The Carbo “Ratcha-matic” is a load-sensing ratchet block that rolls freely in both directions under low loads but automatically engages the ratchet as loads increase. Shifting between the non ratchet & ratchet modes is seamless & the loading point at which this occurs is adjustable.

Provides a good balance between holding power & controlled easing.

Also available:

1)  As an on /off ratchet  – See “Harken, Carbo ratchet – 57mm on/off”

2) With higher holding powers – See “Power ratchets”.
