The Barwalt 1/8" + Hollow Leave-In Tile Spacers are designed for professional and DIY tile installers seeking efficient, reliable spacing solutions. These spacers feature a hollow core that allows grout to flow through and fully fill the joint, eliminating the need for spacer removal. This leave-in design saves time and enables earlier grouting, streamlining the installation process. Made from compressible material, these spacers can flex up to 10% to accommodate variations in tile size and shape. Their extended length makes them ideal for use with radius corners and uneven tile edges, ensuring consistent alignment and spacing. The "+" (cross) style provides stable four-way support during installation.
