Need replacement shoe spring etc

Hello,

Unfortunately, the old rod-style balances like the one in your photo are no longer available but we do carry a suitable replacement. You'll need to measure the length of your balance and weigh the window sash to choose the appropriate length and strength option by following the chart under the description on the S775 product page. You'll also need to replace the balances on both sides of the window at the same time. Thanks for posting!
