The Strofix ellipsoid end cap is an AISI 304 stainless-steel dome that closes the open end of Ø42.4x2 mm railing tube. Supplied with a polished finish.

The rounded ellipsoid profile stands slightly proud of the tube and softens the termination, which suits post tops and handrail ends that people pass close to. It is press-fitted into the tube – no welding or adhesive is needed.

Closing the tube keeps rain and debris out of the hollow section. AISI 304 stainless steel is suitable for standard interior and exterior installations.

Use cases:

  • Closing the top end of a Ø42.4 mm railing post
  • Rounded termination for handrail ends on stairs and landings
  • Sealing the post against rain and debris ingress
  • Softening an exposed post end where people pass close by
  • Finishing prefabricated post assemblies before delivery

FAQ:

What tube does this cap fit?

It fits Ø42.4x2 mm railing tube.

How is it fitted?

It is press-fitted into the tube end. No welding, screws or adhesive are required.

How does it differ from the flat and convex caps?

The ellipsoid cap has the most pronounced dome of the three. The flat cap sits almost level with the tube, the convex cap has a shallow curve, and the ellipsoid stands proud with a rounded profile.

What steel grade is used?

AISI 304 stainless steel with a polished finish.

Will it stay in place outdoors?

Yes. The press fit holds it in the tube. For exposed locations where the cap could be knocked, a welded cap is the more secure option.

About End Caps

An end cap closes the open end of a railing tube, post or crossbar rod, keeping water and dirt out and giving the end a clean, finished look.

Strofix supplies 31 end caps in three families: for Ø42.4 mm tube (flat, convex, ellipsoid, 90° elbow and weld-in caps), for 40 × 40 mm profile (flat and weld-in caps) and for Ø10 and Ø12 mm crossbar rods (15–30 mm high, in flat, ball and droplet shapes).

Most are AISI 304 satin; polished versions, raw weld-in caps and AISI 316 on selected caps complete the range. The correct end cap depends on the profile it closes, the shape and whether it is fitted or welded.
