Nice clamp, but made in China.

Wilton C-clamps are A-1 quality and will not break like cheap knock-offs. They are expensive for a reason; good quality steel and precision manufacturing processes produce a quality product.

My new 4" Wilton 404 clamp (foreground) and my 40+ year old Wilton 4404 deep throat clamp behind it.Glad to see there are still some companies out there that doen`t change something that isn`t broke.My new 4" clamp is just as well built as my old one and it`s even the same color blue! I needed a second heavy duty 4" clamp to use with my existing Wilton clamp and the clamps at local big box stores just don`t cut it if you`ve ever used industrial grade c-clamps. Fast delivery, shipped right away.

Fantastic heavy duty clamp. I work in a welding shop and use these daily. If you're planning to clamp anything other than wood, and you have the cash to spend, these are DEFINITELY worth it. These will literally last for decades.

This C clamp is awesome. I know you should not get gushy about c clamps but this thing saved me so much work. Used it (with a piece of 2x4) to pop the bead on a 230mm wide and a 130 mm motorcycle cruiser tires. I had tried the same thing with 6" clamps and just had lots of frustration before the bead would break. These are big enough to go around the tire, deep enough to reach the bead with a piece of 2x4 and strong enough to just crank them down on the tire. I pop one side first (plywood piece on rim underneath, 2x4 piece on top near bead and crank) then flip it over and do the same on the other side. It helps to have 2 so you can use the 6" clamp to hold it after you get some deflection if you need it.
