Excellent tool!, May 17, 2008
By welderdrew from central Texas

"A very excellent tool! Ive allready bought several and will buy the 20.5" model. I work in industrial construction and these clamps hold up well. Other fitters/welders have asked me about them and I just tell them where the nearest NT store is and they buy them also. Thanks for providing a great tool for a great price! Also excellent for clamping pipe. Great idea!

right clamp for me, April 21, 2008
By sparkymcfab from SPFLD,MA

"I BEEN WELDING AN FABRICATING FOR OVER 24 YRS. MOSTLEY IN JOB SHOPS. I BOUGHT 4 STRONG HAND 12.5 SLIDING CLAMPS 3 AN A HALF YRS AGO WITH THE 2 ATTACHMENTS V BLOCK AN THE THREADED HEAD . I BOUGHT THEM CAUSE OF THE JOB I WAS DOING NEEDED SOMTHING WITH A LOW PROFILE AN SOMTHING THAT YOU CAN APPLY A LOT OF TORQUE USING THE 3/8 DIA ROD THEN YOU HAVE THE HEX HEAD WHERE YOU CAN PUT A WRENCH FOR EXTRA TORQUE. BEING THAT IT SLIDES TO YOUR PROPER HEIGHT AN A DEEP THROAT SO YOU CAN SQUEEZE IT DEEPER. AN MADE OF SOME TUFF MATERIAL, WHERE IT HASN;T TWISTED AN PLATED SO IT DOSNT RUST. WITH THE RIGHT ATTACHMENT YOU CAN INVERT THE SLIDE AN SCREW THE THREADED HEAD IN. AN IT CAN BE USED TO PUSH THE MATERIAL OUT. ALL IN ALL IT IS ONE TUFF CLAMP THAT CAN TAKE THE ABUSE I GIVE IT. AN IF IT EVER GOT MISPLACED LOST OR STOLEN I WOULD NOT HESITATE TO BUY ANOTHER. WELL WORTH THE INVESTMENT"

A dream come true, January 21, 2008
By wrenchspinner from Lone Oak, Tx.

"For the woodworkers out there quick set style clamps have been available for years, yet not so for metal fabricators until now. With their actuation similar to the woodworker guys "pole clamps" or Pony clamps, meaning you can slide your clamp up close to whatever setting you need it at before using the C-clamp style spinner handle to make your final clamping operation quickly and simply this tool provides metal fabricators with a very versatile new tool to make their work MUCH easier! Add in the extender and V-block attachments this fine tool also comes with makes it a very well thought out product .... thanks Strong Hands !"
