Frequently Asked Questions relating to this product:
Question: I am looking to get a 30mm castor, i notice that the product that is listed is hard. I have carpet flooring, would these be adequate?
Castors Unlimited Response: Yes, these castors have a hard wheel which means that they run excellently on carpets and rugs. We also do the opposite to this castor which is a 30mm soft wheel castor which is to be used on hard flooring such as laminate, tiles and wooden flooring. These castors will run smoothly on your carpet and will not cause any damage.
Question: How do i know what stem to use?
Castors Unlimited Response: In order to establish what stem you should order, you need to know two things, 1. the diameter of your current stem, 2. The remaining stem length that is left after the stem is pushed into the castor. After you know this information, its easy! You match up your measurements with our range of stem options and look for your match.

I needed replacement castors for my G-Plan sofa, that were more substantial - with an M8 thread rather than an M6 thread.
Ordering was simple online. The range was good. TI made a phone call to the office regarding order and the service was superb.
Castors fitted and hopefully will last for years!!!

Bought to replace broken castors as originally fitted to our expensive settee! Bought castors, stems and sockets so I knew they would match and fit.

As I was not sure which castors I needed to repair a broken chair, I really valued the expert advice I received, the prompt service and very good value.

I bought a bargain filing cabinet on EBay, and broke one castor on delivery.
I was delighted to find a replacement from Castors Unlimited, and was highly impressed with both pricing and delivery.
Cannot recommend Castors Unlimited enough.

I used these castors under children's boxes full of heavy toys, e.g. Brio. Just the job. They allow us to move the heavy boxes around without lifting. They are strong enough without being intrusive.

My order was 9471, I received order 9470. Close but not close enough. I got the two castors I ordered plus another two, but the person who ordered 4 castors only got two. I thing you should sort this out with no extra cost to either customer.
Castors Unlimited Response: This was a silly mistake that was made in the warehouse and packaging department. This was not done purposely and we sincerely apologised and quickly got the correct orders sent out. We would have never charged any of the customers as this was our company's fault and we took full responsibility and sorted the problem out as soon as we were aware of the situation.
