Roberts Designs L-Shape Trim Matte Black 12mm x 3m Aluminium Tiling Angle

Matte black L-angle from Roberts Designs, 12mm leg on a 3 metre length and commonly listed as 12.5mm. The flat black finish hides fingerprints and scuffing better than a gloss black anodise, which is why it turns up around shower niches and vanity returns. Punched aluminium flange beds into the adhesive; cut it with a mitre saw and a fine-tooth blade to keep the edge clean.
