I wish I would have found these before buying the some of the other brands. They travel very smooth and easy and will hold just about anything that fits between the jaws. Have not needed to combine the two to make a longer clamp but will it be handy at some point. I also have light duty and Hobbie grade clamps from Jorgensen and have been very pleased with all styles. I have somewhere around 40 various length clamps by at least 4 different makers but always reach for these 1st.,,,unless it's a dirty of greasy project then I will grab a blue clamp to keep these cleas. Great product!
