How to adjust cam to unlocked position

Hello, thanks for writing in. I agree that the 15-105 looks like the right pivot shoe for you. Are you trying to remove the pivot shoe from the window? If so, you will need to unhook the channel balance clip and cord from the pivot shoe first. From there, you should be able to unlock the pivot shoe by inserting a screwdriver and rotating the cam. You can take a look at the videos linked on the side for assistance. 

Hm, it sounds like there might be a problem with the balance. I would suggest that we try to figure out what kind of channel balance you have and from there make sure that you have the right spring calibration. If you have a spring that is too heavy duty that could be the source of your issues. In order to do this I will need to see the balances removed from the window. I'll also need to see the stamp or imprint on the metal channel, which indicates the spring strength. 

Balances typically can last up to 15 years, so age could be a factor. Another possible issue could be that the springs have become rusty. Take a look at the video below for assistance with the removal process. Let me know what you find!

Sounds great! I look forward to hearing from you. Happy New Years!

Hello, thank you for your patience. I actually think you'll be needing our Series 770 with the 62-105 hook. These will have to be custom made due to the fact that they are not one of our stock options. I just e-mailed you two custom order links based on the quantities you show in your screenshot. I certainly would think that these new balances would improve the functioning of the window! Please let me know if you have any further questions or if there is anything else I can assist you with. 

I'm afraid we haven't encountered this type of assembly before. Our balances go in straight and the screw goes right into the jamb liner. I confess I'm not 100% certain that ours will work because we haven't dealt with this issue before. I'm very sorry we don't have a better answer for you. Unfortunately we don't have an alternative to offer. 

Sounds good. Please let us know how it works out. We really appreciate your business and hope you will consider us for your future hardware replacement needs. 

Julia isn't here today, but I can help you out from here on. We should have no problem making these balances for you. My only concern is the stamp options in each case; your older balances use a different rating system than ours. I believe you will need the following stamps, in order:

• 1640 balance: 17D (16 through 19 lbs)
• 2840 balance: 29D (23 through 28 lbs)
• 2930 balance: 29C (18 through 23 lbs)
• 2940 balance: 30D (24 through 29 lbs)

I highly recommend weighing each sash to confirm that our stamp options will work for you, since I'm not 100% sure that they will. These are educated guesses on my part, and since custom balances can't be returned for a refund then you really should check.

Assuming I am correct, I will email you four order links and price quotes for the requested quantities. Note that these links will not contain the 15-105 pivot shoes you requested, as they are sold separately. You can just add them to your cart when you're ready to checkout.

Awesome! I'm glad you got everything sorted. If you ever had any follow-up questions, you know where to find me.
