HARKEN 29mm Pivoting Lead Block — Cam-Matic® cleat – 395
HARKEN 29mm Pivoting Lead Block — Cam-Matic® cleat – 395 is Harken cam-cleat hardware designed for fast, positive line control and clean release in sail-control applications.
- Ball-bearing cam action reduces friction for quick engagement.
- V-shaped cam geometry grips line securely with a short downward motion.
- Rounded tooth profiles are designed to hold without unnecessarily cutting line fibers.
- Fast release supports frequent trimming and adjustment.
- Purpose-built Harken geometry integrates with compatible fairleads, risers and bases where applicable.
High-strength pivoting lead blocks with cams are used for halyard controls on larger keelboats and as “head knockers” on dinghies and beachcats for sheeting directly from the boom. Hole spacing and rivet size are the same as Classic models, making upgrades easy.
For best results, confirm the Harken part number and system compatibility before installation, and operate the hardware within Harken’s published line-size and load limits.
