Ellipsis Aluminium Extension Kit - 100cm Extension for Round Rail Balustrade
The Ellipsis extension kit allows you to extend an existing Ellipsis balustrade by 100 cm per module. It connects to the Ellipsis aluminium starter kit or to another extension kit to cover spans of 220 cm, 320 cm or more. It includes 1 pre-assembled round post, a 100x30mm handrail and 5 round Ø16mm rails 100 cm long — the exact dimensions to align perfectly with the starter kit.
Available in gloss black and gloss stainless steel, it maintains the visual consistency of the entire Ellipsis installation. The junction accessories between modules (rail connectors Ellipsis Ø16mm rail connector, handrail connector Ellipsis handrail connector) and the floor fixing hardware are not included — to be ordered separately according to your configuration.

Installation tips
Connection: Position the extension kit in line with the starter kit. Insert the Ø16mm rails into the connectors on the starter kit side, then into the supports on the extension post. Connect the handrail via the Ellipsis handrail connector. If your configuration includes an angle between two sections, use the articulated rail joint and the articulated handrail joint.
Fixing: Secure the post to the floor via its shoe bracket using fixings suitable for your substrate. Align the post with those of the starter kit using a horizontal spirit level before tightening. Once the rails are in place, check that all 5 rails are perfectly horizontal along the entire length of the installation.
Cutting: If your span is not a multiple of 100cm, cut the rails and handrail with a hacksaw or circular saw fitted with an aluminium blade. Deburr the cut edges before inserting into the connectors.
Maintenance and protection
Same maintenance as the starter kit: soapy water annually, rinse with fresh water in coastal environments. Check the tightness of the rail and handrail connectors once a year — thermal variations outdoors can gradually loosen assemblies over time.
WoodUp tip
What to know before buying: this extension kit is only compatible with the ELLIPSIS range and requires an ELLIPSIS starter kit (ID 721) as a base. Each module adds 100cm. For a 3.2m balustrade: 1 starter kit (120cm) + 2 extension kits (2x100cm) = 320cm. Round rail connectors (ID 782) and articulated joints (ID 781) must be ordered separately for junctions between modules and direction changes.
Frequently asked questions
How many extension kits are needed to cover 4 metres with the Ellipsis range?
For 4 metres: 1 starter kit (120cm) + 3 extension kits (100cm each) = 420cm total. Cut the rails and handrail to 400cm on site. Allow for 3 sets of rail connectors Ellipsis Ø16mm rail connector and 3 handrail connectors Ellipsis handrail connector for the 3 junctions between modules.
Can the Ø16mm round rails be cut to fit a span shorter than 100cm?
Yes. Ø16mm aluminium can be cut cleanly with a hacksaw. Cut all rails to the same length to ensure alignment. Always deburr the cut edges with a fine file before inserting into the connectors — burrs can prevent full insertion and weaken the assembly.
Which junction accessories should be ordered between two extension kits?
For each junction between modules: 5 round rail connectors Ø16mm Ellipsis Ø16mm rail connector + 1 Ellipsis handrail connector Ellipsis handrail connector. If the junction includes an angle, replace the straight connectors with 5 articulated rail joints Ellipsis Ø16mm articulated rail joint + 1 articulated handrail joint Ellipsis articulated handrail joint.
Is this extension kit compatible with other aluminium balustrade ranges?
No. The Ellipsis extension kit is only compatible with the WoodUp Ellipsis range (Ø16mm rails, 100x30mm handrail, round posts). It is not compatible with the Quadrum range (16x16mm square rails, 80x30mm handrail, flat posts) or with other brands. Always make sure you order all modules within the same range.
Is the Ellipsis extension kit suitable for outdoor use (terrace, balcony)?
Yes, anodised aluminium is suitable for outdoor exposure without additional treatment. The Ellipsis range is designed for both indoor and outdoor use. In coastal environments exposed to sea spray, a fresh water rinse once a year is sufficient. Visually check the tightness of the junctions between modules after the first winter season outdoors.
