Our Legacy Sash Windows now come with run-through sash horns, for that truly authentic look.

These aren’t just stuck on. They're fully integrated using mechanical joints, with woodgrain foiled end caps that flow seamlessly into the sash. Combine with a slim midrail and the result is a timeless finish that’s hard to beat.

Whether you’re replicating a historic design or elevating a new build with a classic touch... this one's a crowd-pleaser.
