A tale of 7 Cs (alarm boxes)

This video compares the 7 most common C class boxes to be found out there in the wild.
I am just talking in this case about the plastic variety and not the shorrock or other metal boxes.

Hope this video helps some of the younger collectors in their search for C boxes.

Nice little set of boxes! There’s a c box on eBay.

[@audiotron1003]

I hope this inspires you and helps seeing them all together.

I looked for it but couldn't find it

[@mrsecurity]

I’ve got 4 type c boxes now, 2 A1 2 CQR
I’ve also got 2 type S boxes

I've never seen a gardtech one

[@audiotron1003]

There used to be loads in Nottingham. At least 3 alarm companies used them, K alarms, Bar alarm and W E C (West Bridgford Electrical) used them. Red opal and yellow respectively.
I'm happy to make a video for you.

NONE in my home town but theirs tons of c boxes

[@audiotron1003]

Maybe it all depended on what the alarm company preferred. Gardtech made polycarbonate and polypropylene boxes.

[@consha6121]

So did cqr start the c type boxes

[@audiotron1003]

I can't say because long before the plastic boxes there were numerous metal C boxes and at least 2 styles of vents meaning at least 2 manufacturers or one manufacturer that subtly changed the spacing of the vents.

@@audiotron1003 so why did loads of manufacturers start making c type boxes why couldn't they just make their own boxes
