Searching for Tie bar with 2 rollers and 45.5 inches

A quick learner says:
I need replacement tie bars and the hold down nylon clips. Preferably in stainless steel as the building is near the ocean. The picture is of a tie bar originally installed 2015.
The bar is 45.5 inches and had rollers at 7 1/2 inches and 41 3/4 inches
The operator on the window is from Truth so I assume they made the lock? I need 2 of these one for a left handed window and the other right.

Thanks for reaching out to us. I'm afraid we don't have an exact match for your hardware. I recommend taking a look at our 38-919 tie bar and 39-448 tie bar guide. Do you think this could work on your window if you were to move the locking keeper locations on the sash? Look over the specifications and see what you think.

A quick learner says:
Thanks not a bad option.
I have a question is the bar made of stainless steel??
And if so are stainless steel keepers available??

Thanks

We don't sell these parts in a stainless steel version, unfortunately. I am very sorry for the inconvenience.
