High efficiency single pulley with one-way rotation and swivel

The SPIN L1D is a high-efficiency single pulley with an integrated swivel and one-way rotating sheave. Designed for use alongside a descender, it simplifies the setup of heavy-load deviations and haul systems for work at height and rescue. The faceted sheave rotates in one direction only, delivering excellent hauling efficiency while providing additional rope friction for improved control when lowering heavy loads.

Features

• Designed for heavy-load rigging:
  • Ideal for use with a descender when setting up heavy-load deviations and haul systems for work at height and rescue
  • Triple-action opening mechanism allows quick operation, even while wearing gloves
  • Rope can be installed while the pulley remains connected to the anchor
  • Red indicator provides a clear visual warning when the moving side plate is unlocked
  • Special side plate design protects the rope path and allows use with a Prusik friction hitch in progress-capture systems
• High hauling efficiency and controlled lowering:
  • Faceted sheave rotates in one direction only for excellent hauling efficiency
  • Integrated friction zones provide additional braking when lowering heavy loads
• Easy handling:
  • Integrated swivel allows the pulley to orient itself under load
  • Swivel accepts up to three carabiners and allows direct connection of ropes and slings for easier rigging
