balances

Hello! I recommend our Series 600 spiral balance. You will need to measure the outer tube to determine the length. I would also recommend measuring the diameter, just to be sure the Series 600 matches. Please also note that our balance tubes are metal, not plastic. We find these hold up far better. As for tilt latch, start by looking at our 26-243 and 26-244. I recommend checking our measurements to confirm they're the same size.
