PRG023 DG Site Glazed Lock Stile COMpression Block - Black (Hware)

The PRG023 DG Site Glazed Lock Stile Compression Block is a specialised glazing component designed for use with Double Glazed (DG) site-glazed configurations in Alspec ProGlide sliding door systems. Installed within the lock stile profile, the compression block provides a firm internal contact point for the glazing assembly and helps maintain the correct positioning of the glass and glazing gaskets. Its black finish provides a discreet appearance within the aluminium frame. The block also helps minimise vibration and movement within the lock stile while supporting a more consistent compression of the surrounding glazing components. It is suited to commercial and architectural sliding door fabrication and installation where accurate glazing and reliable frame performance are required.
