Top sash guide and balancer

Question

I am looking to purchase top sash guides and balancers. The metal on the balancer is 30" long. There is a stamp on the balancer that says 29 3 BSI ML
thanks!

Thanks for posting. See the S380-30 or S385-30 Channel Balance. The only difference between these two balances is the shoe depth. See below. For a stamp option choose 2930. For the Top Sash Guide see if the 18-171 matches what you seek.

Comparison of the S378, S380 and S385 balance shoes.
