Thanks for posting. Unfortunately, no--using the narrower Series 900 Spiral Balances for a window meant for the 5/8" diameter Series 600 Spiral Balances could result in the 'skinnier' balances breaking or snapping. View our Return Policy here. If the outer tube is 17" long and about 5/8" in diameter, then see our S600-17 instead. |
