18" channel balances for hurricane proof window

A home owner from Florida says:

Hi,

I need to replace a pair of 18" channel balances for a hurricane proof window weighing quite a bit and I am not sure which model to choose. The only references I know are : Channel Balance Top, New Security 19-041 and Channel Balance Shoe, Winged 15-005.

Which model do you recommend?

Best regards,

Thierry

Hi Thierry. We can replace this balance for you, but it will have to be custom made due to its unique nylon fittings, as well as the dual-spring strength stamp code. I am sending you an email with a custom link to order (2) of these balances. If you have any questions or concerns, just ask us here in the discussion thread. Many thanks.

Hi,

thanks for your reply. Are they going to be ½" wide and 5/8" deep?
