Norandex Channel Balances

Hey Richard. This looks like a Series 380 or Series 385 Channel Balance. The only difference between these two kinds of balances is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. To know what length you need, measure the metal channel, but do not include the nylon fittings in this measurement. You'll then need to choose a stamp option. Look for a stamp code on the metal channel. If you're unsure, obtain the exact weight of your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the product page. 

Hey Richard. Yes, all our channel balances come fully assembled out of the box and ready to install.

The difference between the Series 380 and the Series 385 is the depth of the bottom nylon shoe. This can be thought of as the heel-to-toe measurement. For the Series 380, the bottom nylon shoe has a depth of 1". For the Series 385, the shoe is 1-3/32" deep. The picture below illustrates this.

Finally, your stamp option of 3435 is a little weird. Can you provide the exact weight of your window sash? That will tell us what stamp option you should use. Many thanks.

Hey Richard. Thanks for being thorough and checking this. If the shoe depth is 7/8", then I actually recommend we go with custom built balances that have the 15-029 7/8" shoe attached. We'd be happy to do this. I just want to get all the details sorted before I go ahead and write up a quote for you.

• You indicate that there are two different sized window sashes. The balances for each sized sash should correspondingly be different lengths then. We know one set of balances you need are 35" and have a stamp code of 3450. I am assuming this is for the five windows that weighs 20 lbs, though I would double-check this sash weight to be extra safe. Either way, you would need (10) of these balances total, right?
• The smaller window then should have balances of a smaller length and a different stamp option. Please confirm those details for me. Also, I am assuming they have the same nylon fittings as the longer balances. You'll need (2) of these smaller balances. 

From there, we can get this going for you. Thanks for bearing with me, Richard.

Hey Richard. Thanks for confirming those final details. I just sent you an email with two custom links for the following:

•  One link to order (2) 35" balances with the 19-005 Top and 15-029 Bottom Fittings attached, stamped 3410 (which supports a window sash in the weight range of 8 through 13 lbs). 
• One link to order (10) balances of the same length and same fittings, but with a stamp option of 3430 (which supports a window sash in the weight range of 18 through 23 lbs). 

Let me know if you have any questions prior to ordering; note that these custom balances are non-refundable, so it's best to double-check everything one last time before proceeding. If you have trouble removing and re-installing the sash when installing these new balances, see if the guidance video below helps. Thank you too for the very kind words too; it's nice to be able to help people get what they need, especially with balances that are this particular. Let us know if you need anything else!

Sounds good Richard. If you have any other questions, we will be here. Thank you. 

Take a look at our 18-161. Go over the dimensions and see if this matches what you need.

Awesome, Richard. Let me know if you need anything else, and many thanks for your business; we appreciate it.
