Product Description
3mm R420MM Convex Round Mirror Glass – 50mm to 254mm
Premium 3mm R420MM convex round mirror glass, precision cut in the UK for applications requiring a strong wide-angle view. The R420MM (420mm radius of curvature) profile provides a noticeably wider field of view than a gentler R1260 mirror, making it especially useful for compact automotive mirrors, blind-spot mirrors and inspection equipment.
Available from 50mm to 254mm diameter in exact 1mm increments. Each circular mirror is professionally wet finished on the front and back edges and cut to a tolerance of +0/-0.5mm.
FITTING ADHESIVE IS NOT INCLUDED
For secure installation, we recommend U-POL Tiger Seal Black PU Adhesive & Sealant – BUY HERE →. Follow the adhesive manufacturer’s instructions and confirm suitability for your mirror housing and substrate.

R420MM compared with R1260
An R420MM mirror has a stronger convex curve, producing a wider field of view and smaller reflected objects. An R1260 mirror has a gentler curve and a more natural-looking reflection. Always confirm the required radius before ordering.
