The Posi-Lok Internal Flagpole Winch is a heavy-duty stainless steel winch designed to keep internal halyard systems locked exactly where you set them. A patented positive-locking mechanism prevents “flag drift,” so the flag stays put until the crank handle is reinserted and turned. 

Built from #304 stainless steel, the Posi-Lok winch is engineered for demanding commercial, municipal, and institutional flagpoles. It’s compatible with 1/8"–5/32" cable and requires only routine lubrication for long-term, low-maintenance service. 

Available in three sizes, the Posi-Lok system covers internal-halyard aluminum flagpoles from 5" to 8" butt diameters and heights up to 100', making it a direct replacement for many internal winch installations. 

Key Features:

• Positive-locking internal winch – no slipping or gradual flag drop
• #304 stainless steel construction for corrosion resistance in harsh environments 
  
• Works with 1/8"–5/32" stainless cable commonly used in internal halyard systems 
  
• Three sizes to match 5", 6" and 8"+ butt-diameter flagpoles up to 35', 50' and 100' tall 
  
• Mounts with stainless hardware (crank handle sold separately) 
  
• Manufactured in the USA
  

Use this winch when you need secure, precise flag positioning on internal-halyard poles and want a long-term, serviceable solution instead of a basic ratchet or friction winch.
