U Cap Rail for Glass Balustrade – overview
The U Cap Rail (MOD 0301) is a square stainless steel U-profile that is fitted on the top edge of the glass. It protects the edge, links the panels into one line and gives a slim, modern look compared with a round handrail.
MOD 0301 is listed on page 12 of the UNIKIM 2024 catalogue in two sizes. The matching 90° corner is the Cap Rail Corner 90° (MOD 0302); a matte black version is the Black U Cap Rail (MOD 0301).
UNIKIM makes it in its own factory in Ningbo, China. Choose AISI 304 for dry indoor areas and AISI 316 for humid, pool and coastal locations – see 304 vs 316 stainless steel.
