Setting Block 5 x 21 x 100mm x Qty 100 - Black (Hware)

The Setting Block 5 x 21 x 100mm provides a stable interface between glass and aluminium framing during glazing installation. Its 5mm thickness makes it suitable for applications where limited clearance requires a low-profile setting block. The 21mm width and 100mm length provide a broad support surface beneath the glass, helping distribute load and minimise concentrated pressure along the glass edge. The block also creates separation between the glass and aluminium frame, helping reduce the risk of direct contact, edge damage and stress caused by frame movement. Supplied in a quantity of 100 black setting blocks, it is well suited to professional glazing contractors, aluminium fabricators and window and door installers.
