Frequently used in all boat sizes, these non friction rings are song, light, safe and have a high resistance. They're made of hard anodized aluminium and have a Teflon® finish.

Holt / Nautos 28mm Ball Bearing Single Vertical Footblock. Loads in footblocks can be the highest imposed by sheets. Always be sure of loads when ordering this part. Rope locks are intended to do a temporary job. Do not use high loads as a stopper.

Holt 40mm Autoratchet made with advanced carbon composite cheeks, hard anodised CNC’d aluminium sheave for ultimate grip and wear resistance. The sheave activated ratchet is automatically triggered under load with the embedded spring mechanism in the centre of the block.

This organic block is an original concept that gives near zero friction and heat resistance. It combines composite cheeks with aluminium axle, Delrin sheave and balls. This allows maximum performance in racers up to 32ft.

ORGANIC BEARING SYSTEM - Aluminium large central axle provides a lightweight alternative to the Dynamic. Aluminium dissipates heat build up giving excellent performance.
