The Narrow Ferrule Head Block uses a narrow sheave for extremely small control lines and has a ferrule head for soft attachments.
16mm Blocks have a lightweight design and a unique patented bearing system which uses stainless steel balls in a captive, grooved race. Very high working loads in an extremely lightweight block, with the best strength-to-weight ratios around. Use with small synthetic control lines found on high-tech dinghies.
