Ten black large-flange aluminium rivets, 4.8 × 21 mm, for fixing CrystalGuard clear burglar bars to aluminium window frames.
AluminaLock large-flange rivets fix CrystalGuard clear burglar bars securely to aluminium window frames. The large flange spreads the load, and the black finish blends with black frames.
You’ll need a rivet gun and a drill bit matched to the rivet diameter. See our guide on how to install burglar bars on aluminium windows for fixing tips, or let Wonder Bars install clear burglar bars for you.
