Back-to-Back Pull Handle Fixing: M6 or M8, Timber or Glass

Updated 2026-11-05 · RAYEN 雷茵

Most of our door pull handles print the fixing screw and the hole size for each door type. Read those first. The drawing and the door then settle the rest. This guide covers what those figures mean, which handles differ, and what a fitter needs from you.

How does a back-to-back pull handle fix?

One handle goes on each face of the door. The fixing passes through the door at each foot and draws the two handles together, so neither face shows a screw head in normal use. Single fixing works the other way round: one handle on the pull side, with the fixing coming through from the push side and a cover or push plate over it.

Tell us which one you want. Length of fixing depends on door thickness and on whether there is a second handle, so the same model can leave the factory with different fixings.

What hole does each screw need?

• M6 screw, timber door: φ8mm.
• M6 screw, glass door: φ12mm.
• M8 screw, timber door: φ10mm.
• M8 screw, glass door: φ16mm.

Glass takes the larger hole every time. On a glass door, go to the glass door handle hole guide before you do anything else, because the holes must be made before toughening.

Pull handles with M8 fixing

How do you know whether a handle is M6 or M8?

Read the model. Do not assume.

• Length does not decide it. T5580 is 250mm long and M8. T52 reaches 1200mm and is M6.
• The model number does not decide it. T1170 is M6 and G1170 is M8. T2888 is M8 and G2888 is M6.
• Material does not decide it, with one exception so far: every brass handle with a printed screw uses M8. See brass pull handles.

Are there handles with a stepped hole?

Yes. T790 prints outside φ12mm, inside φ8mm, with an M6 screw and an Ø10mm stem. So the hole is not one diameter through the door, and the two faces take different drills. Follow the drawing for that model and do not reuse the numbers from the tables above.

Which handles do not fix through two simple holes?

• T1118 sits on an 80 × 16mm base plate, with centres of P=710mm and P=90mm on its 2000mm version and P=350mm and P=90mm on its 700mm version.
• T5612 sits on a base plate of 58 × 328mm or 60 × 330mm, with P=250mm.
• T2973 has P1=40mm at each end, so each end has its own pair of fixings.
• T2751 also has P=40mm at each end.
• PRE150 is a recessed pull, not a surface handle. It needs a door cutout of 42 × 174mm, or 46mm wide for a 45mm door, and a 26mm recess, with a 20mm variant. Its 50 × 180mm face plate has fixings at P=75mm, twice.

Multi-foot long handles add a hole for every foot. See long entrance door pull handles.

What does the shaded strip on the drawing show?

Many drawings shade a strip beside the handle. That strip is the door. On T790 the 35 printed under it is the door drawn, not a handle size and not a limit on your door. Do not copy it into an order. Projection is the figure that describes the handle.

What should you measure on the door?

• Door thickness at the handle line, including any facing or cladding.
• What the door is made of at each foot. Hollow doors need a solid block where the foot lands.
• Whether something sits inside the door on that line, such as a lock case, a rail or a cable.
• Both faces. Back-to-back holes must be square through the door, so drill from a template on one line. A skewed hole pulls the two handles out of true.
• On a replacement, the old hole size and spacing. A bigger old hole may need a different fixing.

What to write on your order

Write one line per door: model, length, P, screw size, door material, door thickness, and back-to-back or single. For example: T1122, 700mm long, P=615mm, M6, timber door, φ8mm holes, back-to-back pair, plus your door thickness. Where a model gives no fixing size, ask us before you drill and we will confirm it against the drawing.
