I tried the cheaper Confast version of these first, and two bolts in, could see that they were complete doo-doo, immediately stopped using them, and switched to these. The well-known reputation of Redheads are industry-wide for a reason - they work so well! I should’ve just gone with the trusted, tried-n-true brand first and saved myself the wasted money, headache, and mistakes. The specs are exactly what we needed, the quality and design of the product is far superior to Confast’s crap, and they install so much better than anything else I’ve used.
