Glass Door Handle Stem and Glass Thickness: What Has to Match

Updated 2026-11-08 · RAYEN 雷茵

A glass door handle has three sizes that must agree: the stem on the glass, the hole through it, and the thickness of the glass between the two handles. Our glass door handles list the first two. The third comes from the door.

What is the stem on a glass door handle?

The stem is the post that joins the grip to the glass. It presses on the glass face around the hole, with the fixing running through the hole to the handle on the other side. So the stem has to be wider than the hole, to leave a ring of glass under it.

Some worked examples from models whose drawings print the stem diameter:

• G1105: Ø19mm stem, M6 screw, φ12mm hole in glass. The stem overlaps the hole by 3.5mm all round.
• G1131 and G2888: Ø22mm stem, M6, φ12mm. That leaves 5mm all round.
• G1170: Ø25mm stem, M8, φ16mm. That leaves 4.5mm all round.
• G1211: Ø27.2mm stem on a long handle. Its hole size is still to be confirmed on the drawing.

Our guide to glass door handle hole size lists the hole for every model.

How thick is the glass on a glass door?

The glass thickness belongs to the door system: the floor spring or pivot at the bottom and the patch fitting at the top. Ours list it like this.

• D-3015 and D-3016: 8–12mm glass.
• D-1031, D-1051 and DZ-2031: 10–14mm glass.
• D-1042: 10–12mm glass, paired with D-1031.

So a door built on D-1031 with D-1042 is a 10mm to 12mm door, because the patch sets the narrower range. Choose the handle for that glass. Sizes for the springs are in the floor spring size chart, and the top fittings in top pivots and patches.

Why does the handle need the glass thickness?

On a back-to-back pair, the fixing passes through the glass from one handle to the other. Its length depends on the glass, plus any gaskets or sleeves between metal and glass. A fixing that is too short does not pull the two handles tight; one that is too long stops before the handle seats. Our handle pages list the screw and the hole, not a glass range, so tell us the glass thickness on the order and we will match the fixing to it.

What should you check with the glass processor?

• The hole diameter from the handle page, and the hole centres from the drawing.
• The glass thickness, the same figure you give us.
• The distance from each hole to the glass edge, which belongs to the glass specification.
• That all holes are drilled before toughening. Toughened glass cannot be drilled afterwards.

Can one handle suit two glass thicknesses?

Often, with a different fixing. The stem and grip stay the same; the part that changes is inside the hole. If a project mixes 10mm and 12mm doors, put them on separate lines so each set ships with the right fixing.

What should you measure on an existing door?

• Glass thickness, with a caliper at the edge, not a tape.
• The existing hole diameter and centres, if you are replacing a handle.
• The size of any old stem marks on the glass. A smaller stem may leave them visible.

What to write on your order

Write the model, length and centre, screw, hole in glass, glass thickness and finish. For example: G1105, 700mm long, P=640mm, M6, φ12mm hole, 10mm glass, satin stainless, back-to-back pair. If the door system is ours too, add the floor spring model on the same order so we can check the glass range across every fitting.
