This flooring installation tool is designed with an upgraded design that provides either a 1/4 in. or 1/2 in. gap between the floor and the wall, allowing 1 set of tools to meet different gap requirements. Its special triangle design ensures stability, eliminating the need for taping to the wall during installation. This design also helps reduce damage to floors by providing proper expansion spacing, which is suitable for most wood flooring. Made from impact and chemical-resistant plastic, these tools are durable and can be reused multiple times. The kit includes 40 flooring spacers, making it ideal for large-area wooden floor installations, as it significantly improves installation efficiency, saving both time and money. Additionally, these spacers are easy to install and remove from various types of wooden floors in just a few seconds, simplifying the installation process for greater convenience.
