Black U Cap Rail – overview
The Black U Cap Rail is the UNIKIM U cap rail MOD 0301 in a matte black finish. It protects the glass edge and draws a thin black line along the top of the balustrade – a popular look with black spigots, posts and window frames.
The brushed version is the U Cap Rail (MOD 0301); for spigots in the same colour see the Black Glass Spigot (MOD 6100).
Made in stainless steel with a matte black finish; ask for AISI 316 for coastal and pool projects.
