4mm Polycarbonate Corner Connectors?

[irisscientist]

Dear all,

Could anybody please advise where (in the UK) it is possible to purchase strips of 4mm polycarbonate, right angle, corner connectors? I have managed to find some in China at the below URL, but appear unable to find any stockists of such similar items anywhere within the UK? Can anybody please help?

Many advanced thanks for any/all assistance with this matter.
