Precision 80mm Glass Block Alignment Spacers (10mm Joint)
Achieve dead-straight, professional mortar joints and complete structural stability during the installation of 80mm hollow glass blocks. Engineered from high-density rigid polymer, these modular alignment spacers lock every glass block into a perfect grid, preventing sinking, joint sagging, or course drifting while mortar and structural silicone cure.
Uniform 10mm Joint Consistency
Guarantees uniform 10mm mortar spacing across every horizontal bed and vertical joint, ensuring clean sightlines on curved and straight glass block walls alike.
Modular Snap-Off Wings
Supplied as standard 4-way cross spacers. Easily snap off one or two wing tabs by hand or with pliers to create 3-way T-junctions or 2-way perimeter border spacers.
Heavy-Load Structural Polymer
Manufactured from high-density rigid PVC that resists vertical compression under the weight of stacked glass courses, keeping joint depths uniform from bottom to top.
Seamless Mortar Embedment
Designed to embed securely within the mortar or adhesive matrix without inhibiting bond strength or creating hollow voids along structural reinforcement rods.
Estimation Guide: How Many Spacers Do You Need?
As a standard rule of thumb, allow 2 spacers per 1 glass block (a 2:1 ratio) to ensure complete alignment across all internal intersections, courses, and perimeter edges:
