Traditional Sash Horns
Enhance your window by opting for our premium sash horns. The run-through horn utilises mechanical joints rather than welded to allow the horn to be a continuous part of the sash giving the window a more authentic overall look.
You can also choose a deep bottom rail if you want your sliding sash windows to look as close to the original timber version as possible.
