Woodstock W1007 4-Inch Blast Gate for Use with Vacuum/Dust Collectors

Comment: These are junk. I bought 7 of these blast gates and while installing them, four of them came apart. I was not rough with them. Bad glue job or maybe poor glue, but in order to use them, I drilled all four corners and bolted them together. Now I find out they clog very quickly. DO NOT WASTE YOUR MONEY for these blast gates.

Comment: Bought several of these at the same time, wish i hadnt. They are ok for the money but gate slot jams with sawdust very fast nesitating having to unhook hose or tube to clean or else you cant shut the gate. also have had 2 of them come apart (bad glue job??)

Comment: The trouble with the design of this blast gate is there is no way to clean out any accumulated dust. Even with the best dust collector, you will always get some stray dust or debris that accumulates on the gate. Every time you open and close the gate, this dust get packed into the bottom of the gate. Eventually, the gate will not close all the way. As more dust gets trapped, the less the gate can close. I didn't observe this until about a year after using them. I will have to replace all these gates with the metal version which has cut corners that will not allow any dust to get trapped. With the metal version, any dust or debris gets pushed out of the corners when the gate is closed.
Conclusion...dont waste your money on these!

Comment: These gates clog often for me. Since the blast door is contained, chips get jammed into the slot and they keep the door from closing completely. Since these doors cannot be disassembled, they are difficult to clean.

Comment: I got 6 of these and they are a bit flimsy but are probably going to work. One I will have to glue a little as it came apart on one corner. But for the price, it seems worth it.
