Need New Pivot Shoe & Spiral Balance

Question

My measure on the spiral tube is 5/8 x 28 5/8. On the pivot shoe is 1 1/4 wide and 1/2 thick

If the pivot shoe is indeed 1-1/4" wide and 1/2" thick, see our 15-046. If the spiral balance's outer tube is indeed 5/8" in diameter, then you need a Series 600. If the outer tube is in fact 28-5/8" long, round up to 29". Just be sure to remove all the hardware from the window to confirm these dimensions.
