Box Sash timber window hardware

Traditional box sash window hardware

Caldwell’s sash window hardware range extends beyond our selection of conventional decorative and functional products. Alongside these ranges, we are also able to supply box sash window hardware, proving customers with hardware solutions for more traditional box sash window configurations.

Box sash windows are vertical sliding windows nominally built using traditional hardware products. They are typically installed in period properties, or buildings located in conservation areas where traditional aesthetics are prioritised. Using either iron cast or lead weights, we manufacture and supply pulleys (two be used two per sash) for balancing box sash windows. Additionally, we can supply a range of traditional decorative hardware appearances to achieve the ultimate levels of authenticity.
