In aerial cable installations, the choice of clamp at a corner depends on how much straight pull you have before the bend. If the straight pull length (the 6M strand pull) is very short—less than three meters—the straight suspension clamps are used at the corner. This setup avoids forcing the cable to make a tight bend with insufficient support, helps maintain the proper bend radius, and reduces stress concentrations on the strand as it negotiates the corner. When the pull length is longer than three meters, a different corner clamp arrangement is appropriate to accommodate the longer straight run and still maintain proper tension and bend recovery. So, the rule is to install straight suspension clamps at corners when the 6M strand pull is under three meters.
