    • The BB250B , BB500B and BB750B models are for soft vangs and have an Additional Shackle at the Brake Bottom for Vang Attachment
    • To install, you will need (a) cordage (Sold Separately) to run through the brake (b) a turning block (Sold Separately) at or near the chainplates and (c) a way to tension the line at the cockpit such as a spare winch or a block and tackle (Sold Separately)
