Interlock window crank Seattle

Question

Dear Swisco,

I am looking for a replacement for a window crank mechanism shown in the attached photos and that has printing on it, "Interlock(TM) world patents made in New Zealand design pat. pending". In addition to showing pictures of the upper and lower sides of the (removed) crank mechanism, I also show the bar linkage (which works fine) that remains attached to the window.

Thank you for any help with finding a replacement!
Best,
Wyeth

Hi, Wyeth.

It looks like you have our 39-091 and 39-092 operators but you'll need to re-use your old link arms since ROTO discontinued them and offered no substitute. Look these parts over and let me know if you had any questions.
