Oval Railing Base Flange with 2 Fixing Holes, Ø33.7–50.8 mm Tube
The Oval Railing Base Flange with 2 Fixing Holes, Ø33.7–50.8 mm Tube (MOD 1911) is a narrow, oval stainless steel base flange with two fixing holes and a set screw in the tube socket. Its slim shape fits where a round flange is too wide, such as narrow edges and stair stringers.
MOD 1911 is listed on page 33 of the UNIKIM 2024 catalogue as part of our railing base range. 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.

Installation notes
- Fix the base with anchors that suit the floor: chemical anchors in concrete, through-bolts in steel, or structural screws into solid timber.
- Check that the floor or stringer can carry the guard loads before you choose the anchors.
- Check the guard height for your project in our glass railing code requirements guide.
