Hello,
My window balancers are inverted balances with T-locks and are stamped with the number "27B" as shown. I need 6 replacement T-locks to repair 2 window sashes and keep an extra pair in reserve.
The T-locks have the top anchoring portion broken away (~14 year-old windows) and I need to know if your 15-195B part will work with these balancers.
I measured the existing T-lock and it looks to be very close to the diagram you have on the site. The width I measure = 0.473", which is slightly wider than the 15/32 (0.469") specified in your part diagram.
Can you confirm these are the correct replacement parts, please?
Many thanks,
DominicĀ
