This inward offset Porta Winch is built to convert standard trailer stake pockets into secure anchor points for 4" winch straps. Its design allows clearance for track-mounted tarp systems, making it the ideal choice for covered flatbed trailers.

With a 5,500 lb working load limit, this winch provides more secure tension than traditional ratchet straps, and won’t vibrate loose like clamp-on winches. Portable, legal, and easy to reposition — it's a trusted solution for dynamic cargo securement on the road.

Key Features:

• Stake Pocket Compatibility: Easily installs into standard trailer stake pockets with no permanent mounting required.
• Inward Offset Design: Clears track-mounted tarp systems by sitting closer to the trailer body.
• 5,500 lb Working Load Limit: Handles heavy-duty tie-down requirements with confidence.
• Secure & Legal: 3-bar stake pocket design meets industry regulations and prevents winch movement during transport.
• Portable Configuration: Easily relocatable to fit any load setup along the trailer’s length.

For tensioning, the WSTDA recommends in section 4.3.5 that "When using any winch, the winch mandrel shall have a minimum of two (2) and a maximum of four (4) wraps of webbing. Two to four wraps will appear like four to eight layers of webbing. Less than two wraps may result in strap slippage; more than four will place unnecessary strain on the winch. Excessive straps of webbing on the mandrel may reduce the working load limit (WLL) of the winch and may interfere with proper operation."
