The Snapa Rafter Top Glazing Bar is extruded as a low cost budget glazing bar for polycarbonate sheets. The Snapa glazing bar works well with 10mm, 16mm and 25mm Axiome® multiwall or twinwall polycarbonate sheet. Whilst Snapa PVC glazing bars are ideal for smaller DIY type projects, where greater longevity and strength are required, our Alukap®-XR aluminium glazing bars are recommended.
