Review on 🔧 M D Building Products 67106 Extension Pieces for Enhanced Performance and Compatibility by Patrick Cox

This product is poorly made and difficult to assemble. The company does not provide installation instructions anywhere. The only way to get it together after about 45 minutes of trial and error was to turn it over and gradually pinch it along the back with pliers. I have no idea how you could add this to the set threshold. And our method chewed up the back. Of course it's hidden after installation, but still not ideal. Quality is a disappointment. Everything was fine after installation, but given low stars due to installation issues.
