28x100mm Wedge Glazing Packers are tapered packers designed for installations where a wider and longer wedge is needed to help secure the glass unit inside the sash or frame. The 28mm width suits wider glazing channels, while the 100mm length provides more contact along the edge of the unit than shorter 80mm wedges. This makes them useful when the installer wants a steadier wedging action across a longer section, rather than a small local adjustment. The wedge profile helps take up movement as it is inserted, allowing the glazed unit to sit more firmly in place. These packers are useful for toe-and-heel work on doors, sash correction, and general glazing adjustment where the unit needs to be held securely before final beading. Made from polypropylene, WP28B wedge packers provide firm support and are suitable for professional window, door, conservatory, and curtain walling installations. Why installers choose 28x100mm Wedge Glazing Packers: Wider 28mm profile for broader glazing channels Longer 100mm body for steadier wedging pressure Helps tighten and stabilise sealed units inside the frame Useful for sash alignment and door adjustment work Helps reduce unwanted movement before final beading Polypropylene construction for durable trade use These 28x100mm wedge glazing packers are a practical option when the installation needs a wider wedge with extra length for more controlled glass positioning.
