"Since the first time I used the brackets, I haven't looked back! Cuts installation time and no more messing around with shims! Also, hangs solid core doors with ease!"
"We have tried the Ultimate Bracket prior to recommending to our clients. Our firm provides technical advice to both government departments and contractors, with our focus primarily in the Canadian Arctic. The Ultimate Bracket not only decreases labour cost, has less bulk for storage and shipping, provides easy future adjustment, if needed, but also when used on exterior door and window installs, reduces thermal bridge and decreases opportunity for insulation voids often found when using conventional wood shim applications."
"I am not a contractor but I am a bit of an engineering/fabricator nerd and when I see something that makes total sense and is efficient and noteworthy, I cheer! This is one of those game changer inventions! No shims, no fuss, no mess — a quick, clean and efficient install. Most importantly, my contractor was able to insulate completely around the window without any voids."
"Grant-Marion Construction has been using the bracket since its inception in 2016. Mike initially fabricated this bracket for installing interior pre-hung doors. Since then, Mike has made 2 modifications based on our/other company's recommendations for window installations. As a result, Mike has developed a great product that saves our company time / money and has eliminated any callbacks related to window buildouts bowing."
"I'm a contractor in the Cornwall area installing doors and Windows and love this product. I use the Ultimate Brackets on a daily basis. Strongly recommend as it's a no brainer."
