Can someone help me identify the manufacturer for my windows I have the warranty info s/n 142 - 533323 NorCal 100/200/HUD UM111 AAMA/NWWDA 101/I.s.2-97 CMBSO1-79/CAWM 301 And the other number that are located on a tag on inside of the window

CODE:ALS Rating:HS-LC25 Series 270 MST 6060

  • Hi there, based on the information you provided, the first string of letters and numbers are related to the window's conformance to standards laid out by NorCal, AAMA, and CMBSO and do not act as identifiers of the window series or manufacturer. On the other hand, the second tag info does provide better hints to where your window comes from. The window is a 270 Series Light Commercial PG25 horizontal slider. At the very least, you can approach window sellers/manufacturers in your area whether they have/had a 270 Slider Series. – AnonyTech Oct 22 '18 at 17:40
