I need new balances for my Malta double hung windows














Perfect. I think I have an idea, though it would have to be custom made. I'm thinking of using our S750-24 channel balance, but attaching our 15-159 shoe at the bottom. We would also be using the 23R stamp option; a pair of balances with this option can carry a window sash weight of 10 through 18 pounds. Finally, your top and bottom sash will require two different S clips at the top in order to install; the top sash will need the 19-029 and the bottom sash will need the 19-030. Please review this hardware and let me know if you think this will work in your jamb.
If so, we'll email you a custom order link for your review. Let us know if you have any questions!





If the S70 balance is 24" long the shoe would reach the bottom of the top sash.








Anyone know what the ORIGINAL balance on this Malta window was like? Was it a channel, spiral, pulley, constant force, etc. type? And to HP Bridgewater (or anyone else) can you get any code or model numbers off your old original balance? I have a couple of these that are failing and would like to try and rebuild them with new springs, hardware, string, etc. My house was built in 1987 with I think Malta Classic View, double hung, clad wood frames and compression jamb liners. Any help or direction would be greatly appreciated.





I think I have exactly the same problem with my Malta windows. If I sent pictures , they would be EXACTLY as in the above thread.
I'm trying to understand how many channel balances (and model#) I would need for the following window sizes:
2 windows- The visible glass in the upper and lower sash are both 34 7/8 " wide and 19 1/2" high
1 window -The visible glass in the upper and lower sash are both 34 7/8 " wide and 23 1/2" high
From the parts list you mentioned in the earlier thread I think I would need a total of :
12 channel balances (what model #'s -- S750-??)
12 15-159 pivot shoes (to replace all existing)
?? top s-clip 19-029 ? How many would I need ?
?? bottom S-clip 19-030 ? (how many would I need ?
I'd like to give this fix a try -- can you please confirm I'm on the right "track" ? and advise missing details ?
Thanks , In advance !!

Hi, Mike! Thanks for the detailed information. Hopefully we can help.
These are estimations from the dimensions you gave. You should compare them to the ones you have in the existing windows just to be 100% sure.
For the 34-7/8" x 19-1/2" window, I recommend eight S750-20 balances with a stamp of 19HD, which can support sashes weighing 17 through 22 pounds.
For the 24-7/8" x 23-1/2" window, you will need four S750-24 balances with a stamp of 23HD, which can support 18 through 22 pounds.
We would specially attach the 15-159 shoe to each of the above window balances. I also recommend ordering six of the 19-029 and six of the 19-030.
Please look over this information and let me know what you think. If it looks good to you, let me know and I'll email a special order link for the above balances.

Looks good to me.I will order and see how we do.
Regards,
Mike




Hi there, I'm afraid we don't sell jambs, just balances to install into them. Sorry for the inconvenience.

Have a question for you or any of the other folks that completed the conversion. Do these balances need to be special ordered or can I just order the correct length 750 series channels, a bunch of the listed s-clips, shoes, and tilt pins and piece it together myself. Seems as though I should just be able to order and put together but in a couple of spots Paul, you mentioned placing a custom order/request.



You can absolutely buy these parts separately and assemble it yourself, yes. Just note that any balance altered in this way cannot be returned for a refund. Custom made balances are also non-refundable, though, so in that aspect there isn't much difference.
I'm also required by policy to tell you to make sure to wear safety glasses and goggles before you attempt any alterations like you have in mind. These cords are under a lot of tension and if they slip out of your grip, that plastic could shatter. I've seen people I've worked with get hit in the eye in such circumstances, so take all necessary precautions. You definitely want to use a bench vice to keep that cord secure before you try swapping anything out.

My compression jambs are the same as the pictures at beginning of this thread. How do you remove them without destroying those vinyl jambs any further ? They appear to be able to come out, but I see NO fasteners of any kind, and do not want to break them.
This thread seems to show that your channel balances can/will work in this series of windows. I need several different quantities and sizes.
Thanks in advance.



A lot of older window jamb liners are only held in place by the pressure provided by the sash itself. Once the sash is removed, they can be taken out by hand.
Of course, depending on how old it is, that's easier said than done. Age and sun exposure can make the vinyl much more brittle than it was when it was originally installed. With that in mind, you have to be extra careful not to crack it during removal. One trick I've seen is putting soapy water on the sill at the bottom of the jamb liner to help lubricate its removal. You could try that and see how it goes.
