Cavity Tray Cleaner


Designed to rest within the cavity, on top of the cavity tray, the Cavity Tray Cleaner is a tool that enables the collection of fallen mortar between cavities of newly built walls.

The design is formed from a train-like mould, that connects in a series. It is erectable and collapsible within minutes, with strong male and female profiles to keep the Cavity Tray Cleaner in one piece. Designed with a scorpion-like tail, which ensures mortar doesn't track back into the tray.


The Cavity Tray Cleaners are manufactured in UK using Recycled Plastic.

    This is a game changer for the industry. I’ve been laying for over 30 years now and cleaning out cavity’s has always been a pain with making sure weep holes aren’t blocked and muck build up. This system works a treat. Simple to put together and so easy to take out and empty at the end of the day. No more shoving your whole arm in the cavity to make sure it’s clean!
    Will definitely be getting another set to use. 100% recommended.

    Been bricklaying for 35 years now

    Been bricklaying for 35 years now. Currently house bashing. I got a 20m kit. All turned up quickly and all in good order. It fits together well and is easy to use. It's saves a lot of time and fits well in 50 mm cavity. Had it for two weeks now. Working very well I am happy with it.

    Worth every penny

    Bought a set about a week ago only used lightly for 4 course of concrete blockwork but worked a treat saved using a batten and leaving cleaning holes. Overall its cut my cavity cleaning time by more than half meaning i'm able to lay more blocks 💵💵 as long as clean out regularly and treat them with care they will last years. already bought my second set, well worth the money.
