Used these to maintain gap around the floor in my garage. I used to have to for when I payed laminete floor but must have thrown away. These are a must to ensure things don’t move when ur assembling the floor. If using the underpayment the floor seems to stay where u put it while assembling. But these are a bonus to ensure you maintain a gap around the perimeter.
The spacers were helpful for making sure the tiles were properly installed.
