Same jamming problem as others

I've had the same problem with them jamming when the slot gets blocked as others. I found sawing a 1cm long slot in the bottom corners helps solve this, the holes will let air leak in, reducing by a small amount the suction in the system. But I guess the little blast of incoming air blows the slot clear as the hole certainly isn't big enough for jammed sawdust to be pushed out. I might try just drilling an even smaller 4mm hole in the bottom corners on my next few gates and see if this still blows the slot clear.

These are great with an modification

I have had a number of these in my system for years and have always suffered the design fault, namely the slot blocking with dust causing the gate to stay partially open reducing the suction in the system. Time after time I had to remove the gates and clean the slots.
Well done Kerin for his suggestion, cutting a small corner off the gate at the lowest point. The gates all shut well now and when they are open the loss of suction is unnoticeable.

OK (ish)

As others have mentioned, a design fault means that the dust gets trapped in the slot of the blast gate, and after a while it prevents the gate from closing properly.
I didn't want to spend a lot on the metal ones, so I just cut off the bottom corner, about a 20mm triangle, to expose the blast gate. Now every time you shut the gate, it pushes the dust out of the slot.
It's not ideal, as you lose a little bit of suction when the gate is open, but it reduces the number of times you have to clean the slot out.

Amazed at Axminster selling these

I am extremely surprised at Axminster selling these, they are not up to the standards that Axminster seem exact in the products they sell.
I would have thought that after seeing a couple of poor reviews they would look into what the problem is but they haven't done that on this occasion. You are much better off buying the metal blast gates, they do cost £6 more than these plastic ones but they perform very well and do not have any leakages that I can hear or see from dust flowing.

Poor design.

The other review mentions these leaking, and I've been using these for sometime. They jamb very quickly with dust resulting in them not shutting down properly. This is a design fault where they clearly have not been tested before offering them to the public. If you could open them then they could be cleared, unfortunately they are sealed. So not a good buy.
