To Continue a Good Thing 
If your dust collection hose is at an end, and you still have a machine to travel to, then this splice is your answer. Both ends were at 4" , the hose fit nicely, and the wire clamps attached snuggly.The splice allows you to use up all the hose, no matter the length of the run.
Fits well!
This is a well made splicer. Looks and feels solid. Fits very nicely.
Works as expected
It's plastic and joins my two pieces of 4" hose. Does what it's supposed to. I don't see a difference between mfgs so make sure you get it on sale.
A piece of plastic
It's a piece of plastic. How can you review a piece of plastic. It does what it is suppose to do.
Basic Accessory
Easy to use when connecting some shorter pieces of hose. Be sure to clamp tightly.
