Connector for square rails 16*16
Connector for square rails 16x16mm Quadrum range — straight junction between two square rails end to end. Finishes gloss black or gloss stainless steel. Compatible with WoodUp Quadrum range. Sold per unit. 5 connectors per junction required. Not compatible with Ellipsis range.
Connector for Square Rails 16x16mm – Straight Junction Quadrum Range
This connector ensures a straight-line junction between two sections of square rails 16x16mm from the Quadrum range. It is used at each straight-line connection between modules — between a starter kit and an extension kit, or between two extension kits. Each junction requires 5 connectors (one per horizontal rail) and 1 Quadrum handrail connector to ensure complete continuity of the balustrade.
Available in gloss black and gloss stainless steel finishes, it maintains the visual consistency of the Quadrum assembly. For junctions with a change of direction, this straight connector must be replaced by articulated rail connectors Articulated connector for 16x16mm Quadrum rails. It is exclusively compatible with the 16x16mm square rails from the Quadrum range — not interchangeable with the Ø16mm round rails from the Ellipsis range.

Key points
- ✓ Straight junction — for in-line connections between Quadrum modules
- ✓ 16x16mm Quadrum — exact dimensions of WoodUp square rails
- ✓ 5 connectors per junction — one per rail, to be paired with 1 MC connector
- ✓ Consistent finishes — gloss black or gloss stainless steel
- ✓ For angles: use Articulated connector for 16x16mm Quadrum rails — articulated connector instead of this straight connector
- ✓ Not compatible with Ellipsis — Ø16mm round rails have a different profile
Installation tips
Order 5 connectors per straight junction between modules. Cut rail ends perpendicularly with a hacksaw and deburr the edges before insertion. First insert all rails into their connectors without tightening, check horizontal alignment along the entire length of the installation, then tighten progressively. For a perfectly invisible junction, position the connectors at a post — the assembly will be enclosed by the rail support.
Maintenance and protection
Clean with soapy water annually. Check connector tightness once a year — thermal expansion outdoors may slightly loosen screwed assemblies. Rinse with fresh water in marine environments.
Frequently asked questions
How many rail connectors are needed to join 3 Quadrum modules?
3 modules (1 starter kit + 2 extension kits) have 2 junctions: you therefore need 10 square rail connectors (5 per junction, 16x16mm Quadrum rail connector) and 2 Quadrum handrail connectors. Plan this purchase when ordering the kits to avoid any delay on site.
Is this connector compatible with the Ø16mm round rails from the Ellipsis range?
No. This connector is designed for 16x16mm square rails from the Quadrum range. The Ø16mm round rails from the Ellipsis range have a round profile — their dedicated connectors are the Ø16mm Ellipsis rail connector. Even if the nominal dimensions appear similar, the internal housings of the connectors are different.
Can this connector be used to extend a rail that is too short?
Technically yes — two rail sections can be joined end to end with this connector, even outside of a junction between modules. For a stable result, position the connector at a post support rather than mid-span. A rail joined mid-span without support may flex slightly under lateral load.
What is the difference between the straight connector 16x16mm Quadrum rail connector and the articulated connector?
The 16x16mm Quadrum rail connector provides a straight-line junction (180°). The articulated connector allows a variable angle for changes of direction. Use the 16x16mm Quadrum rail connector for all in-line junctions between modules, and Articulated connector for 16x16mm Quadrum rails only for angles. They are not interchangeable.
