I recently purchased a home with vinyl windows, and I am looking to replace several broken vent loks. I have looked for a brand name on and around the window but found none. Also, I have taken a vent lok to several stores which sell vinyl windows (Home Depot, Lowe's, Sears, and some mom & pop shops), and no one can ID it. In general, who would be best ID the lok, and specifically, is there anyone in Denver that I can be referred to?
Thanks
