## Description

These window sash lifters are designed for double-hung windows to assist with smooth, balanced operation. Each lifter is made from die-cast zinc for strength, density, and resistance to deformation under repeated use. The set includes 4 units, sized at 4 in. Wide by 3/4 in. High, with a center hole spacing of 3-5/16 in. to match standard window frame configurations. Their pure white finish blends discreetly with light-colored frames, supporting clean visual integration. They function by bearing part of the sash weight during vertical movement, reducing manual effort when opening or closing. Installation relies on existing screw holes and original hardware to maintain structural alignment and load-bearing integrity. These components do not include fasteners and are intended for replacement in compatible double-hung systems where original mounting points remain intact. They are not suitable for retrofitting non-standard or modified frames without verifying dimensional compatibility and load requirements.

• Pure white finish blends seamlessly with light-colored frames
• Die-cast zinc construction ensures durability and strength
• Support sash weight during vertical movement for easy operation
