The extension clamp may include a yoke and an extension rod extending from the yoke. The yoke may include a first end and a second end, the first end having first and second rod engaging portions and a channel between the first and second rod engaging portions for encompassing a fastener, and the second end being spaced apart from the first end. The first and second rod engaging portions may be configured and dimensioned to secure the extension clamp to the elongated rod.
