Description Brummel Hooks – Adjustable These Adjustable Brummel Hooks have been a revelation for some pilots, who could never get their speed system lengths set up correctly! The adjustable Brummel hooks are great if you need to adjust the length of your speed system quickly or regularly, for example if you fly more than one glider. Simply thread your speed line through the three holes of the adjustable Brummel hook, pass it back through the first loop and it locks off, without the need for a knot. Adjustable Brummel hooks are sold in pairs.
