An underlay lens sits beneath the outer viewing window in a blast cabinet, absorbing abrasive impact and shielding the primary window from pitting and scratches. When the underlay lens becomes obscured, it is replaced instead of the costly window, dramatically lowering maintenance costs and extending cabinet lifespan in industrial sandblasting environments.

Replacement frequency depends on media type, blasting pressure, and usage hours. In heavy production environments, underlay lenses may need replacement every few hours of use. Inspect the lens regularly - replace it when visibility is noticeably reduced or surface pitting makes safe operation difficult.

Underlay lenses are a low-cost consumable alternative to replacing the primary cabinet window. They take the abrasive damage first, preserving the structural window beneath. Replacing an underlay lens takes seconds and costs a fraction of window replacement, making them the preferred maintenance solution in production shops.
