    4" trunking

    I've got a load of 4" trunking which is minus all the bits to join it together and hold the lid on. The joiners are no problems as I can get those. It's just the brackets to hold the lid on I'm struggling to find. No matter how google I use. Does anybody know where you can get them from?
