Dear Charlie,
We will arrange to make 2 samples and about the completed time, i will reply to you later.
In addition, pls check the below reply for your requirement.
Also, as an additional requirement for a future product, this Castor will be used without the Mandrel parts.
The Mandel and Cone would be removed and the Castor would be bolted directing to the product.
The Castor Mounting Rail on the future product is 40x40 SHS.
Could we please request that the M12x80 Mandrel Bolt shank/thread dimension be made to accommodate this requirement.
Pls check the attached print.
Thanks!
