Jorgensen's Pony Pipe Clamp Fixtures provide the most affordable way to outfit your shop with the many bar clamps you need to complete almost any project. Use ordinary black iron pipe (threaded on one end) to make clamps of any length. Note that each clamp head set can be used on as many different lengths of pipe as you choose; thus a half-dozen fixtures can effectively do the work of hundreds of dollars' worth of 2', 3', and 4' clamps. Minimize the effect of pipe's flexibility by placing clamps alternately above and below glued-up panels. Each head & tail 2-piece set makes one clamp.
