IRWIN Tools QUICK-GRIP Handi-Clamp, 4-Inch (1799213)

Easy to use, grips well, reasonable price. I'd buy again.

Seriously lacks holding power when compared to the previous gen of irwin's handiclamp. Save ur money and get the irwin 59400CD instead

Ótimo material, recomendo

These light duty clamps are great as a "third hand" for holding parts in alignment for subsequent final clamping with say screw type clamps. Overall the handi-grip is light and operates easily with one hand, smoothly loading and locking thanks to a fine pitch ratchet mechanism. Even though the handi-clamp frame members are all plastic the tool is ruggedly built and surprisingly rigid. However, the fine teeth on the metal ratchet mechanism can be overloaded if the average guy uses his full grip strength to achieve "extreme" gripping (clamping compression) loads. As well, if this is done there will be little clearance for your fingers to trip the ratchet unlatching lever between the tool's hand grips (i.e. a screw driver blade may be needed to trip the locking lever to unload the clamp). As an example In woodworking these Irwin handi-clamps will generally NOT develop the force needed on a caul to properly compress larger glue joints. In sum, don't expect that these light plastic handi-grips to be "Vise-Grip" or C-clamp substitutes -- they are not in that league. Again, this is a light tool to be used with one hand for quickly setting initial part alignment. Depending on your application, additional clamping tools may be required to assure satisfactory final clamping loads.

Really not good clamps, probably the worst Irwin. If you clamp something that is not parallels, the yellow tips just fly off!
