Edge, Offset or Centre Pivot Floor Spring: How to Choose

Updated 2026-11-09 · RAYEN 雷茵

What do edge, offset and centre pivot mean?

All three describe where the spindle sits under the door.

• Edge pivot: the spindle sits close to the hinge-side edge. The door swings much like a hinged door.
• Offset pivot: the spindle is set in from the edge, so the door turns a little inside its own width.
• Centre pivot: the spindle sits near the middle of the leaf. Part of the door swings each way as it turns.

The exact distance from spindle to edge is on each model's drawing, not in the name. Ask for it before you cut the door or set out the floor.

Which models sit at which position?

The position is in the Chinese model name.

• Edge: D-1031 (glass), D-1033, D-1067, D-3002, D-3013, D-3016 (glass).
• Offset: D-1032, D-1051 (glass), D-1068, D-5061, D-5062, D-5063.
• Offset or centre: D-3001, D-3012, D-3015 (glass).
• Centre: DZ-2031 (glass), DZ-2039, DZ-2086, DZ-2087.

The overhead closers follow the same names. T-1073 and T-1075 are offset, and T-1076 and T-1077 are centre.

What changes with the position?

Two things stand out in the chart.

Opening angle. Every edge and offset model reads 125°. Every model that can run on a centre pivot reads 360°. The walls, frame and stops around the door still set how far it opens in practice.

Width. At the same weight, centre pivots reach less. DZ-2086 and D-1032 both come in 60kg and 100kg grades with EN3 and EN4, yet the centre model reaches ≤650mm and ≤750mm, against ≤800mm and ≤1100mm. On a centre-pivot door, check with us how the width applies.

When does the position not matter?

Two pairs share every rating, so the choice rests on the door alone.

• D-1033 (edge) and D-1032 (offset): 60kg or 100kg, ≤800mm or ≤1100mm, door ≥42mm, EN3/EN4.
• D-1067 (edge) and D-1068 (offset): 200kg or 300kg, ≤1350mm or ≤1500mm, door ≥60mm, EN6/EN7.

Centre pivot overhead closers

If the floor cannot take a unit, T-1077 gives a centre pivot from the top of the door: 150kg or 200kg, ≤1000mm or ≤1100mm, door ≥45mm. That is wider than any centre-pivot floor spring at the same thickness.

What should you measure?

• Door weight, thickness and height.
• Where you want the turning line, marked on the door drawing.
• Width from that line to the door edge.
• Walls, glass screens or furniture inside the swing, both ways for a double-action door.

A worked example

A 45mm timber door weighs 90kg and measures 1000mm from the turning line to the edge. On an edge or offset pivot, D-1033.100, D-1032.100, D-5062.100 and D-5063.100 all fit. On a centre pivot the choice narrows. DZ-2087.150 stops at ≤850mm, but DZ-2087.200 reaches ≤1000mm, exactly this width, on a grade rated for 200kg with EN5. DZ-2039 needs a door of ≥60mm. From above, T-1077.150 fits at 150kg and ≤1000mm. With the door right at the width limit, send us the drawing before choosing.

Does the position matter for glass doors?

Yes, and it carries through to the top patch. The glass floor springs cover every position: D-1031 and D-3016 are edge pivot, D-1051 is offset, D-3015 runs offset or centre, and DZ-2031 is centre. The top patches are named for a position too: D-1042 and D-3018 are edge-pivot patches, D-3017 is offset and D-1043 is centre. D-1043 is also listed with the offset D-1051, so confirm that pair with us. See top pivots and patches.

What is the next step?

Open the floor spring selector and enter weight, width and thickness. Then send the door drawing, with the turning line marked, to [email protected], and we return the drawing of the unit with its spindle position. If you would rather talk it through, WhatsApp the factory owner. The number is on the contact page.
