I recently ordered 30 of the 4003 Toggle Latch clamps from thetoggleclampfactory website. The price for these clamps, including shipping to Canada, was less than I could find at any local vendor. I placed the order on December 4, and fully expected at least 2 weeks for the clamps to arrive. To my pleasant surprise, the clamps arrived on December 10!! That is fantastic service!! And when the clamps arrived, they look stronger and better made than the ones I had been purchasing locally. Even though I have not had a chance to install and use them to test the durability, I am sure they will be superior to the clamps I have been purchasing locally. As long as the price remains the same, I will be purchasing all of my clamps from thetoggleclampfactory.
