We’re not exactly sure what advantage the split-head design on Jet’s Double Header C-clamp gives, but it definitely looks different than most C-clamps.  Instead of two clamping points, the Double Header gives you three points, presumably to spread around the tool’s 1,500 pounds of clamping force.

The Double Header comes with non-marring pads on each split head, to minimize damage to your workpiece.  Jet designed these clamps with a maximum capacity of 4″ and a throat depth of 2-1/8″.

So far, we can only find ’em at Amazon.  There you’ll pay about $40 for a six-pack.

    Funny, is this really a new inovation, or just a gimmick.

    Any one see a real use for this over the old fashion one.

    When you join planks edge to edge, as for a table top, you must also use cauls to keep the top flat. This clamp is made to sit on the junction between two boards and apply just enough pressure to keep the joint level.

    Bessey makes dual headed bar clamps – maybe C-Clamps too.
    I saw some at Lowes:


    Can’t think of a good use for them.

    Sprackle Nice call, I think that is an excellent idea

    I own one of these, and now know what to do with it. Thanks Sprackle, I’ll try that on my next glue-up.

    The reason for this tool is to keep the clamp from torquing to one side. Did you ever find an old c-clamp that when you ran the threaded rod closed it didn’t actually hit the center of the top of the clamp? That’s because someone twisted that clamp. This one won’t do that.

    They are handy for offset clamping.
