Great product! I originally bought a 90 degree Kreg jig for this job, which broke because I couldn't clamp the T-connections. I quickly return the clip to the store and test another one in the store which broke quickly after the first use. I've searched all over the internet for a suitable clamp but reviews have shown that the clamps are not a true 90 degree angle. In the end I found these aluminum alloy rectangular clips and I can tell you that these clips are the best for slicing bread. The clamps are very versatile and allow you to move the clamp anchor at a 90 degree angle along the aluminum alloy rod. Also the mention of the clamp left no trace of where I used the clamps. I know the price seems high compared to other clips but they are TOTALLY worth it.
