I wanted to write you a letter and tell you how great the Device was that sealed the floor where we had an existing 4” core hole thru the floor. The device was extremely easy to install and it only took about 30 seconds to install it. The design is perfect, it is flush with the floor, it is fire rated and carpet will go over the top of it and not be noticed.
