Allenco windows
balances have 3 stamped codes: 2430; B.S.I.; DJ
dimensions: 26" from the bottom of the plastic foot to the tip of the plastic guide.
2 widths the side with the stamps is 9/16" and side that's open is not quite 11/16" but it's also bent so I'm not really sure.
the height is 5/8"
I need about 50 of these.
