4 Inch Mortar Spacers

4 Inch Mortar Spacers

Our 4 Inch Mortar Spacers are specifically designed for the installation of Premiere 3 7/8″ thick glass block in U.S. sizing. These spacers are ideal for creating straight glass block windows or walls, where no curves are required. They provide a consistent 1/4″ spacing around each block, ensuring even joints as you mortar your glass blocks together. Compatible with all of our 4″ thick glass block offerings, these spacers ensure a clean and professional installation.

Using spacers is the easiest way to maintain uniform joints during your glass block installation. At Glass Block Warehouse, we offer cost-effective glass block spacers for both residential and commercial projects. With our spacers, you can install glass blocks quickly and evenly, creating consistent joint thicknesses.

Please note that these spacers are not compatible with the Vetripieno® Series glass blocks.
