2-In-1 Pistol Grip Clamp Set (2 each of 12'' and 24'') SAVE $60!

• Easy to apply pressure—just squeeze the pistol grip to tighten.
• To loosen, trip the trigger release and slide the clamp open.
• Clamping heads slip off easily without tools so the clamp can be used as a spreader, or for linking the clamps for use as a frame clamp.
• When used as a framing clamp, the perpendicular clamp can be pivoted along the axis of its bar, allowing for an incredible variety of clamping positions.
• Steel bar for rigidity and tight clamping power.
• Polymer clamping mechanisms with no-mar rubber clamping pads.

I really like one-handed speed clamps, and these have a lot going for them. They have a thicker beam than the usual quick-grips (minimizing flexing of heads under pressure), they have spring-loaded reversible end jaws for spreading, and they can interlock  to make a poor-man's carving vise, although I have not tried out the last feature. The sale price for four really can't be beat. The only problem I've had with them so far is one defective end jaw, which pops off the end of the bar under clamping pressure: Rockler is sending me a replacement. The plastic resin jaws do make me worry about breakage under clamping pressure, but this is true of most speed clamps and so far no problems (grip strength being the limiting factor in applying clamping pressure with this style clamp).
