BLASI – Glazing blocks 80 x 12 x 3 mm
The BLASI glazing blocks 80 x 12 x 3 mm are precision-engineered spacers designed for BLASI automatic revolving door systems requiring intermediate glass thickness support. Measuring 80 mm long, 12 mm wide, and 3 mm thick, these blocks provide stable positioning for medium-thickness glass while ensuring vibration-free mounting during continuous door rotation. The narrow profile optimizes space within slim door frames while maintaining excellent load distribution. Essential for glass alignment, edge protection, and door balance, these glazing blocks serve as the perfect replacement to restore factory mounting precision and structural integrity.
Product Details
The BLASI glazing blocks 80 x 12 x 3 mm offer balanced support characteristics for automatic revolving door systems with their 3 mm thickness and narrow 12 mm width. The 80 mm length provides adequate contact area for secure glass positioning within space-optimized aluminum door wing profiles common in modern architectural designs. This configuration ensures uniform pressure distribution that prevents glass movement, edge chipping, or misalignment during high-speed rotation in commercial environments.
Manufactured from durable, high-compression materials, these glazing blocks maintain dimensional stability through continuous operational cycles without deformation. Proper glass support eliminates vibration, rattling, and premature failure that compromises door performance and safety. Worn or mismatched glazing blocks lead to balance issues and glass damage. Installing genuine BLASI 80 x 12 x 3 mm blocks restores original mounting specifications, ensuring glass panels remain perfectly positioned, structurally secure, and visually flawless while maintaining smooth operation and premium appearance in demanding high-traffic installations.
