If you want the best!
I work with metal. Cutting, welding, fabricating. I needed another clamp (I have 7 c clamps already).This Wilton columbian, is by far the best of all. It is heavy. If you desire quality. You will be impressed. This clamp is drop forged which is far superior to a cast c clamp.

Wilton quality. Works well for my purpose
Wilton quality. Works well for compressing truck brake calipers. So far I’ve tried it on ford and Ram 2500s and fits well. I’ve been able to compress the caliper pistons without much effort so it’s worked well for my intended purpose.

These ARE the Real Deal!
If you are a professional in the iron/ metal working industry These are the clamps you need to buy/ work with! I began working in industry in the 1970s and 80s and these rival the quality of tools that were available to us back then. Solid, over 4” deep and acme thrd clamping rod exceeds 3/4” dia.

Serious clampage!
These are seriously strong c-clamps. I don't know why I expected different, but when I read that it has a 6" opening I wasn't expecting it to be over 12" total. So it's bigger than I expected. Still, excellent clamp.

Bu ürün wilton değil üzerinde hiçbir markalama yok kutuda made in china yazıyor sağlam güzel duruyor ama işçilik zayıf karşılık kısmı düz değil markaya aldanarak aldım ama gereksiz oldu
