Window balance and sash guard replacements

We located a similar top sash guide. Have a look at our 18-196. You will need to carefully compare your measurements with ours to see if this is a match. For your balances, start off with taking a look at our S380-29. Confirm the depth of your bottom balance shoe measures 1". If it happens to measure closer to 1-3/32", you may want to consider going with our S385-29 instead. Whichever one chosen will go with a 2840 option to correspond with your stamping of "28 4".
