tilt corner key

I'm afraid we don't have a storm window corner that matches your exact dimensions, but our 95-232 comes very close. It's 5/32" thick like yours, but 15/64" wide. Granted, that's only 1/64" off from 7/32", so it might not be the end of the world, but these storm corners are so specific that I thought it was worth mentioning. Either way, it's definitely our best option. Look it over and let me know what you think.
