These are aluminum glazing beads that are used to glaze in insulated glass panels into existing old Weathershield casement window sashes. These are for 5/8" thick IG applications and Weathershield stopped carrying these last month. There are thousands of windows in my area made like this and I know I would be using them a lot. Weathershield has discontinued them due to the window design age.
Sticks of these usually come in 14'ft sticks. Let me know if you can get them. Thank you.
