Traco often uses the 26-390 and 26-391 tilt latches, but it's hard to tell from your photo if these match. You will need to carefully go over our dimensions and compare them to your own measurements to confirm if they're the same.
For your balance system, see our Series 180 coil spring. This may be all you need. You will need number stamped on the old coil spring to find the best match. |
