In brief
- SR-AR-3 is not a leg but an adapter: it lets a castor be fitted into a 30 × 30 mm square steel profile.
- The part is made of polyamide, grey in colour.
- The manufacturer declares 200 kg for three pieces – the lowest load rating in this whole product group.
- It levels nothing on its own: the height and the setting depend on the castor you fit into it.

Expansion adapter (30x30 mm) SR-AR-3 – how to choose the right one
The SR-AR-3 expansion adapter is used to fit a castor into a 30 × 30 mm square profile. It is made of grey polyamide, and the declared load rating for a set of three pieces is 200 kg.
It is an adaptor between the open profile of the structure and the castor stem. Where the frame ends in an empty profile, the adapter gives the castor a seating point that the furniture manufacturer did not provide for at the welding stage.
When selecting, look at two things: the actual dimension of the profile and the weight that is to be moved. Two hundred kilograms spread over three points is the level of a back-of-house trolley or a light rack, not of an appliance filled with water or product.
How to match the leg to the profile, the load and the unevenness of the floor – we explained it in the selection guide for this category.
Where it works
- Trolleys and mobile racks on a 30 × 30 mm frame
- Changing feet for castors in a finished structure
- Frames left with an open profile underneath
- Light back-of-house furniture moved around within a room
FAQ
Frequently asked questions
Have not found your answer? Give the profile, the load and the adjustment range – we will select the leg.
Ask a questionHow does an expansion adapter differ from an adjustable leg?
The adapter levels nothing – its only job is to take the castor stem and transfer the load to the profile. A leg is chosen when the appliance is to stand still, an adapter when it is to move.
Will SR-AR-3 fit a 35 × 35 mm profile?
No, this version is described for 30 × 30 mm only. For larger profiles SR-AR-4 is provided, covering 35 × 35 and 40 × 40 mm.
Which castor fits this adapter?
The data sheet gives neither the type nor the stem diameter, so it is worth confirming the castor match before ordering. That is the most common source of error with this part.
