old thorn 2d square light fittings key

[elsparko]

anyone know the size of the heads of these? is it 8mm? cant remember and need to order 1

Is that the triangle security bolt you mean? A 5mm 1/4 drive socket fits or might be 5.5mm but one or other.

 

[elsparko]

yea the triangle bolt, ive tried my long noses but just doesnt want to loosen!, are they only 5mm?

3 bits of metal/nails elastic band and a pair of pliers, having an equal force on each face helps.

 

[elsparko]

anyone got one of these lying about that they could take a measurement from?

IT is a nightmare with long nose pliers - it is security after all.
There may be someone who can measure against a socket but if I remember correctly it is 5 or 5.5mm Go prepared with the range of sizes and you won't fail - or order a key as above.

It's 5.5mm

Use your hex keys. The hex gives the right triangle for them. Not sure of exact size.

Coughtrie orange handle security key does the trick

I have had similar issues with lamposts in the past.

I purchased a pair of cheap meterbox keys. The are a peice of metal folded into a triangle shape. You can use a pair of pliers to open the key to fit any triangle size.
