The TFloor Spacers can be used to install any laminate wood flooring, vinyl plank flooring, engineered hardwood, bamboo, or any other floating floor material. Using these spacers will ensure that your installation maintains the correct expansion gap between the floor and your walls. Even when the sheet rock is high. Unlike other wedge spacers which slip, tip over and get stuck, the TFloor spacers always stay firmly in place, and maintain a consistent gap using their unique t-shape design. And when you are finished, they are easy to remove. TFloor Spacers can be used for any floating flooring material which requires an expansion gap of 1/4"- 3/8". You can also combine two spacers back to back, turned on their side for an 1/2" expansion gap. Each case of 12 spacers is sufficient for areas of approximately 500 ft2, while 2-3 packs are recommended for larger installations.
