Unger's ErgoTec soft rubber replacement blade fits standard squeegee channels on window cleaning tools, sized 24 inch / 55 cm. The soft rubber compound conforms to uneven glass surfaces for a cleaner, more complete wipe, and stays flexible in cooler temperatures where stiffer blades lose performance. Reduced friction makes for smoother, more consistent strokes on the pull. Ships in a resealable blister pack that keeps the replacement rubber in good condition until installed.
