Product Notice(s)

*For maximum carpet protection, rolling-wheel areas should be double glued to prevent carpet stretching and carpet delamination caused by shear forces and friction. Notes: Scrim backing or other raw materials may be changed without prior notice when shortages occur or when technology advancements become available to improve product performance. Typical product properties are derived from averages resulting from usual manufacturing tolerances. Such variances will not affect product quality or performance.

**Not applicable to separate carpet cushion. Carpet must be tested in composition with cushion.
