Single Action or Double Action Door Closer: How to Choose

Updated 2026-11-05 · RAYEN 雷茵

What is the difference?

Single action means the door opens in one direction. It closes into a rebate or a stop on the frame, and the stop ends its travel.

Double action means the door swings both ways. It passes through the closed position and comes to rest in the centre of the opening. A frame stop on one side would block the swing, so a double-action door has none.

That one fact usually settles it. Look at the frame. If there is a stop, you are buying single action, unless you plan to remove it.

What should you check on the door?

• Which way the door opens today, and which way it must open after the work.
• Whether the frame has a stop or a rebate.
• Door weight, and width from the spindle to the door edge.
• Door thickness, or glass thickness on a frameless door.
• How far it must open. Look for walls and furniture in the swing.
• Whether it must stay open by itself.

Which RAYEN models are single action?

Both are concealed cam closers with a slide arm and track. They are listed under overhead door closers.

Read the first column. Yes means double action. T-1078 comes in 60kg and 80kg grades. T-1079 comes in 100kg and 120kg grades. Both reach ≤800mm in the first grade and ≤1000mm in the second, open to 125° and hold open at 90°. T-1078 needs a door of ≥42mm, and T-1079 needs ≥45mm.

Which RAYEN models are double action?

All 19 floor springs, plus T-1073, T-1075, T-1076 and T-1077.

Two columns are worth a second look.

Max opening angle reads 125° or 360°. The 360° figure sits on models that run on a centre pivot, such as DZ-2086. Edge and offset models read 125°. The walls and frame around the door still set the real limit.

The closing valve and closing force are blank on D-3001, D-3002, D-3012, D-3013, D-3015 and D-3016. If you want to set the closing speed of a double-action door, pick a model that lists both.

Does double action change the size you pick?

No. You size a double-action unit the same way, on door weight and width from spindle to edge. The floor spring size chart lists every model and grade.

What does change is the pair of limits you can reach. Single action stops at 120kg and ≤1000mm. Double action runs to 600kg on D-3001, and to ≤1500mm on D-1067.

Two worked examples

A restaurant kitchen door

Staff push through it both ways with their hands full. It is a 45mm timber door, 70kg, 850mm from spindle to edge, on an offset pivot. D-5062.100 fits: 100kg, ≤1000mm, door of ≥42mm. D-5062.60 stops at 60kg, so it fails on weight.

An office door with a frame stop

It opens one way into the room. It is a 45mm timber door, 70kg, 900mm from spindle to edge. T-1078.80 fits: 80kg, ≤1000mm, door of ≥42mm. T-1078.60 fails on weight and on width.

What about frameless glass?

Glass doors here are double action. D-1031, D-1051, D-3015, D-3016 and DZ-2031 are rated by glass thickness. The single-action models are rated by door thickness, for timber and metal doors.

What should you write on the order?

• Model with grade, such as T-1078.80.
• Single action or double action, in words.
• Door material, thickness, weight, and width from spindle to edge.
• Whether the frame has a stop.
• Finish: satin stainless or matt black.
• Quantity, plus a top pivot or top patch if you order a floor spring.
