HOW TO SET UP THE FRAME STARIGHTENER
Frames and bodies are bent and distorted by collision with a relatively large area of the car bearing the impact. However, the correction procedure utilizes, powerful, concentrated loads at key points which can cause local crushing of frame members, etc., if these points are not property padded to spread the load over a large area. Illustration of recommended anchoring procedures are shown below for efficient use of the under body anchoring System.
Box frames and channel sections should be padded with short pieces of angles iron to prevent damage to the corner of the section when a chain is wrapped a­round the frame section.

For a diagonal pull, the underbody anchoring system provides atachment to both rocker panels, for better efficiency and less damage. The anchoring loads are spread across both sides of the car.

For pulling on one side only, it is best to attach the cross tube to both rocker panels. Anchor your body straightener to the cross tube. This will prevent unwanted rolling of the underbody clamps on the pinch weld.
The underbody clamp secures to the pinch welds allows more versatile positioning of the body straightener.
