Convex push-in end cap for 48.3 mm balustrade tube with M8 thread, AISI 304 satin

Convex push-in end cap is an element that masks openings in stainless steel balustrade tubes. Thanks to precise fitting to 48.3 mm diameter tube, installation involves simply pushing the end cap into the profile interior — without welding or gluing. The central M8 thread enables subsequent mounting of handrail brackets, decorative balls or other terminal elements, providing great flexibility when designing balcony, terrace and stair balustrades.

The convex surface gives the balustrade an aesthetic, rounded finish, which looks professional whilst effectively protecting the tube interior from rainwater and dirt ingress. The knurled shank ensures secure seating in the tube and eliminates the risk of accidental end cap dislodgement.

Technical parameters

Material and resistance

The end cap is made of AISI 304 stainless steel — a grade commonly used in external and internal balustrade systems. This steel is characterised by high corrosion resistance, guaranteeing many years of durability even in demanding atmospheric conditions. The satin surface finish masks minor scratches occurring during transport and installation, whilst harmoniously complementing other elements of the 48.3 mm balustrade system.

Application

The end cap is intended for use in stainless steel balustrade systems based on Ø 48.3 mm round tube — in balcony, terrace, and stair balustrades alike. The M8 thread allows mounting of additional accessories in the central hole, such as handrail brackets or decorative elements. This is a practical solution for installation companies carrying out comprehensive installations of stainless steel balustrade systems.
