Install this Rip Scale Upgrade Kit and in about a half-hour, you'll be instantly setting rip cut dimensions with lightning speed and matchless precision.\n\nA powerful magnetic strip attached to the top of each rail holds your choice of a short or long precision Stainless-Steel scale that is graduated in both, 32nds and 16ths. Choose the long 45� scale when measuring cuts between 6-1/2" from the left of the blade to 38-1/2" from the right. Scales will also read in opposite direction, except numbers will be upside-down. Or, the short 16� scale when measuring cuts between 6-1/2" from the left of the blade to 9-1/2" from the right.\n\nZeroing-adjustments are easily made by simply sliding the steel scales on their magnetic holders. Once positioned, they will remain where you put them without shifting.\n\nThe kit includes: A new 17-1/2" Front Rail for your main table � (3) 7-1/2" Front Rails for your extension tables � 16" Long Stainless-Steel Scale � 45" Long Stainless-Steel Scale � Wide, Easy-to-read Scale Indicator, plus � Complete Instructions and All Required Installation Hardware.\n\nNote: For use with MARK V 520 Pro Fence System Only.\n\n
