These Gold Hog mats are pre-cut to 12" wide. They have been "gently used" but are free from any major blemishes or defects. There were used at a commercial mining operation for a short time and they are are in great shape. We pre-cut each mat to 12 1/32" to 12 1/16". We cut them slightly larger than 12" since every sluice may have some variation in width.
