Hi, My channel balance measures 9/16" wide and 28" long. Only marking on the balance says "2740DG". I think it is either a s351 or s390 but I'm not sure. Please let me know if you need any more info. Thank you.

Hi. I ordered the 2710 and the Window is too heavy. Is there any way I can make the counter balance stronger or do I have to reorder. It won't hold the window open. Thanks.

All of our windows are the same brand and style. Aluminum, probably put in around 1990. But some of the channel tops and shoes have what I call "wings" sticking out to the sides and some do not (see pics). How do I know which ones I should get? Are they interchangeable?

I need to replace some non-tilt channel balances. These are 28" 2730. I'm guessing they are the 350 series - but can tell for sure (tops and bottoms). Please advise.

I looked up this part on your site. The model on the metal channel is 27 C BSI. Please help me identify which one I need. Thanks so much.

We need 8 tilt channel balances. The number stamped on the side is 27200H. 29". Please see pictures. Thank you.

Hello. I think I got it but since I've never done this I figured I'd ask. I narrowed my channel down to 28" SERIES 390 CHANNEL BALANCE with the 2740 option. (28-inch/pd/Series-390-Channel-Balances/S390-28) I measured my shoe and it's 1 1/16. I saw 15-002 measures the same. My channel is 9/16" x 28" ... (cont.)

Good morning, I am trying to replace this channel balance for my home that was built in 1996. From metal end to metal end it is 28 inches long. the window is 30.5 inches high by 48 inches wide

Hi, The channel balance springs have broken on two windows and I suspect two more will probably fail soon. I plan to purchase (4) pairs of channel balances. These are stamped with BSI 2730. The aluminum rail is 28" long. Please advise on replacement parts. Thanks! Linsey

Is this a 390? It is 28 inches long and the stamped number is 2740. It looks like your replacement part does not have a rolled edge. Does that make a difference?

We are looking for window balancers with these sizes; 3070 bsi 2780 bsi 3970 bsi 2760 bsi Can you Help? Thanks Steve

For Alenco windows. The metal is 28 1/4 inches long. I will need 14 window channel balances and also 20 take out clips (in case I break some clips trying to install them). Have attached photos. Need part numbers and prices to place order.

Hello! We are trying to track down some parts for our older Alenco windows. we had some glass replaced and we think they broke the balance when that happened since the windows won't stay open. Can you assist us in tracking down what we need? Thank you sooo much!!! Lorie

The string on my balance broke and I am looking for a replacement. I cannot seem to figure out which would work best. It is 1/2" x 28". The markings say 2712 BSI RE. Can you please recommend a replacement?

Based on the ends of the window balances, I am not sure of which are the correct parts... the sashes weigh approx 18 Lbs... Please help... Thanks John

We purchased 24 of your S390-28, option 2740 balances. They are much thinner than our original balances (see attached photos of our balances next to yours). Can you help us with these replacements?

Hi, Please help me by telling me what I need to purchase/replace so that windows can be opened. Past homeowner left window channel balances off the windows so they could be closed. I looked at them.
