Hello, You are correct, theses balances are no longer made. The correct thickness of the balance tube is 5/8" not 3/8". You need to add the plastic cover for thickness. You can use Series 500-18" red tip balance with 17-012 bracket. These brackets hook on to the balance spiral. To install these balances, you would drop them from the top on the side of the sash. Use a 33-017 screw to attach the balance tubes at the top. Now raise the sash and have someone hold it up while you attach the bottom bracket 17-012 with the self drilling screws you have while the U-shape opening corrals the spiral. With your finger bring up the spiral to the bracket and attach the 75-005 tool and turn the spiral clockwise three turns and hook it to the fork of the bracket. Repeat the other side and try the sash. If sash creeps down, raise and hold up the sash and give the balances another turn or two. |

Hey, Steve. Removing oxidization is going to depend which window parts are oxidized. Which parts are giving you trouble? Generally, you can rub or soak metals in anti-corrosive lubrication oils. WD-40, PB B'laster, and Loctite Naval Jelly are good choices. I had a stubborn customer insist once that kerosene is ideal. I think motor oil might work, even, in a pinch. For lighter oils like PB B'laster and WD-40, you can even leave them to soak overnight. Generally, your best bet is to soak a cloth or cotton-ball in oil and wrap the rusty part, so that you maintain constant contact between the rust and oil. On a larger surface, that's obviously not a good option, unless you want to soak a bath towel in WD-40, or something. In that case, a thin layer wiped across the metal surface (and left for fifteen minutes to an hour) is better than nothing. Always follow the directions for any anti-oxidization product you use. Naval Jelly, for example, will corrode metal if applied for longer than 15 minutes. If you need more specific advice, you might want to update us with a photo of the oxidization you need to treat. |
