Ideal when welding patch repairs in floors, wings, door skins, or when assembling fabricated panels on reskinning projects. The intergrips will clamp flat, curved or even pressed ribbed panels & are designed to leave only a small gap which will allow full penetration of the weld. Once the two sections are tack welded together, the wing nut is slackened, the toggle bar removed & the clamp lifted from the job prior to the final welding.
