Review on QUICK GRIP Throat C Clamp - Essential Tools 225134 for Optimal SEO by Brody Jacobs

I needed deep C clamps and bought two at the store for my drill press. What I didn't realize until first use is that the clamping section is very high and can get in the way. I have switched to deep Bessey C clamps which only have a 1/3 protrusion at the clamp. Bessey CM34DR 3" x 4-1/2" Deep Malleable C Clamp. The Irwin is well made and the lead thread allows for a very quick clamp change. The threads also appear to be plated, but I still use WD-40 to prevent rust. WD-40 is one of those taxpayer funded products (for the US Navy) that is still the best rust removal and prevention product available at any price point.
