Setting Block 8 x 29 x 75mm x Bag Of 50 - Black (Hware)

The Setting Block 8 x 29 x 75mm is a professional glazing accessory designed to provide stable support beneath glass units during installation. Its 29mm width makes it suitable for compatible wider glazing channels commonly found in commercial aluminium framing, shopfronts and sliding door systems. The high-density elastomeric construction provides a durable interface between the glass and aluminium frame, helping distribute the glass load and reduce concentrated pressure on the glass edge. The 8mm thickness also provides clearance between the glass and frame base, supporting proper drainage and helping prevent moisture from becoming trapped beneath the glass. Supplied as a bag of 50 black setting blocks, it is suitable for glazing contractors, aluminium fabricators and professional window and door installers.
