Peachtree Non-tilt Balancers, 2448 and 3660

I need replacements for two different size balances for my Peachtree non-tilt Ariel windows.

One size is marked 3660 L J Caldwell. This one measures 9/16" wide X 5/8" deep with a 26 1/4" overall length. The metal on the long edges of the U-channel is doubled over.

The other is marked 2448 BSI and measures 9/16" wide X 5/8" deep X 20 1/4" overall length. This does not have the doubled over edges. The plugs to retain the cords on the 2448's are white as opposed to black and not anchored with a screw as are the ones for the 3660 balances.

Since I removed the broken units, I can provide images if they are needed.


Please advise what the replacement part numbers for these are, at your earliest convenience. At this time, I need a minimum of 3 pair of the 3660 and 2 pair of the 2448.

Many thanks,
John

The two upper balances are the 2448 units. The stationary block & tackle is anchored with a pin through the sides of the U-channel.

The lower three images are of the 3660 units. The stationary block & tackle is anchored in the U-channel with both a reverse bent tab and a screw (not shown).
