Glass Door Floor Springs by Glass Thickness: 8mm, 10mm, 12mm and 14mm

Updated 2026-11-08 · RAYEN 雷茵

What should you know before choosing?

• Glass thickness, as the glazier will supply it.
• Door weight. Ask the glazier for the weight of the finished panel.
• Width from the spindle centre to the door edge.
• Pivot position: edge, offset or centre.
• Whether you need to set the closing speed.

In the photos, each glass model has a slot along its body that takes the bottom edge of the glass. That slot is what the glass range describes.

The chart lists only the models rated by glass thickness. Timber and metal models are in the floor spring size chart.

How do the glass models differ?

• D-1031: edge pivot, 10–14mm glass, 60kg at ≤750mm or 100kg at ≤1000mm, EN3/EN4, 45# steel.
• D-1051: offset pivot, 10–14mm, 120kg at ≤1100mm or 150kg at ≤1200mm, EN4/EN5, 45# steel.
• DZ-2031: centre pivot, 10–14mm, 150kg at ≤800mm or 200kg at ≤900mm, EN3/EN4, 45# steel.
• D-3015: offset or centre pivot, 8–12mm, 100kg at ≤600mm or 150kg at ≤800mm, 304 stainless.
• D-3016: edge pivot, 8–12mm, 80kg at ≤800mm or 120kg at ≤1000mm, 304 stainless.

The 8–12mm models have a 304 stainless body but lists no closing valve or closing force. The 10–14mm models have both. If you need to set the closing speed on 10mm or 12mm glass, choose from the 10–14mm models.

Which top patch goes with each?

• D-1042 goes with D-1031, for 10–12mm glass.
• D-1043 goes with DZ-2031 and D-1051. No glass range is printed for it, so confirm 14mm with us.
• D-3017 goes with D-3015, and the glass needs a 107 × 53.5mm cut-out.
• D-3018 goes with D-3016, and the glass needs a 107 × 70.5mm cut-out.

Toughened glass cannot be cut after toughening, so pass the cut-out to the glazier with the glass order.

What fits each glass thickness?

8mm glass

D-3015 or D-3016, with their own top patches. They carry up to 150kg and 120kg in the heavier grade.

10mm or 12mm glass

Every glass model fits. Choose by weight, width and pivot position.

14mm glass

D-1031, D-1051 or DZ-2031. The top patch is the open question: D-1042 stops at 12mm and D-1043 prints no range. Ask us before you order 14mm glass.

A worked example

A hotel entrance has a frameless door in 12mm glass, 130kg by the glazier's figure, 1150mm from spindle to edge, on an offset pivot. D-1051.150 fits: 10–14mm glass, 150kg, ≤1200mm, EN5. The .120 grade fails on both weight and width. DZ-2031 carries the weight but stops at ≤900mm. Pair it with D-1043, and confirm 12mm on that patch with us.

The handles and locks on the same door need holes in the glass too. See glass door handle hole sizes and send both drawings to the glazier together.

Which material and finish?

Every glass model and every top patch comes in satin stainless or matt black. The 10–14mm floor springs have a 45# steel body, the 8–12mm ones 304 stainless, and the top patches are 304 stainless. Order the floor spring and the patch in the same finish, so the top and bottom of the door match. If the door has handles in another finish, settle that before the order, because the patch faces sit at eye level on the top corner.

What should you write on the order?

• Floor spring model with grade, such as D-1051.150.
• Glass thickness.
• Door weight and width from spindle to edge.
• Top patch model.
• Finish: satin stainless or matt black, the same on both parts.
• A note that cut-outs follow our drawing.
