Setup and Installation

Tools Required:
- Wrench set (appropriate size for bolts and nuts)
- Measuring tape
- Marker or pencil
Installation Steps:
- Identify Mounting Location: Choose a suitable location on the trailer's A-frame. The adapter can be mounted on either the right or left side. Ensure there is sufficient clearance for the sway control unit and its operation. The adapter is compatible with 2-inch x 3-inch A-frame trailers.
- Position the Adapter Plates: Place one adapter plate on the inside of the trailer frame and the other on the outside, aligning the holes. The plate with the sway control ball should face outwards.
- Insert Bolts: Insert the provided bolts through the aligned holes in both adapter plates and the trailer frame.
- Secure with Nuts: Thread the nuts onto the bolts and hand-tighten them.
- Final Tightening: Using a wrench, securely tighten all nuts. Ensure the adapter plates are firmly clamped to the trailer frame and do not move. Do not overtighten, but ensure a snug fit to prevent movement during towing.
- Attach Sway Control Unit: Once the adapter is securely installed, attach your sway control unit to the ball mount on the adapter according to the sway control manufacturer's instructions.
