16mm Triple Air Block with Becket

16mm blocks offer very high working loads in an extremely small, lightweight block. These diminutive blocks feature a patented bearing system using stainless balls in a captive, grooved race and provide an honest 250lbs (113kg) safe working load.

They are perfect for the new, smaller synthetic control lines found on high-tech dinghies and are the obvious choice for competitive racers. The 404 uses an O-ring to keep the line in the sheave during intermittent loading.

Use for:
  • Dinghy control lines
  • Spinnaker pole trip lines
  • Big boat leech lines
  • Outhauls
  • Downhauls
  • Cunninghams
  • Traveler Controls
  • Halyards on prams
Specifications:
  • Sheave: 16mm (5/8")
  • Length: 57mm (2 1/4")
  • Weight: 43g (1.5oz)
  • Max Line: 5mm (7/32")
  • Safe Working Load: 318kg (700lb)
  • Breaking Strength: 544kg (1200lb)
