Set of four Jorgensen 7284 steel I-bar clamps, 84" (7 ft) clamping capacity. Multiple-disc clutch design — locks instantly, holds without slipping. Rated 7,000 lb clamping force. Ductile cast iron castings, cold-drawn steel screw with Acme threads. The 72-series is discontinued and getting hard to find — the heavy-duty originals. Light surface rust on the bars from storage; clutches and screws all work as they should. $300 for the set of four. Cash, pickup only in St. Albert. Text 780-289-9463. Available Mon, Tue, Thu, and Saturday mornings.
