I use one of the knock of tial gates. They look indentical but are different in the inside. The tial uses a higher quality material for the diaphram. Other then that they are the same gate.

The reason I went wiith the cheap unit instead of the good one is the fact the both are rebuildable. Dont get me wrong I didnt buy it so I could rebuild it all the time, I went with it because the weak part of it is the same as the tial. So when/if I need to rebuild it I call tial and get the diaphram and I have a gate that is exactly the same for less then 1/2 the price.


So far the gate works just as it should and I haven't had a real complaint about it.


The bad part is buying this stuff hurts the real companies that went through the trouble to design it.
On the other hand there isn't any real reason to charge such a high price for a part that costs like a 1/5 of that to have made.
