help Identifying a channel.

A handy person from Glen Head New york says:

My channel is 25" long and has a width of 1/2" and has B.S.I. 2430 stamped on it.

Tom from SWISCO responded:
Thank you for posting! I've narrowed this balance down between two options: either our Series 380 or Series 385 channel balances. Now, personally, I think it's closer to our Series 385 balance, but you should double check just to make sure.

The major differences between these balances can be found in their bottom shoes. The Series 380 uses our 15-005 while the Series 385 uses our 15-004. Carefully compare their dimensions to your own shoe and see which is closer.
15-004 and 15-005
