Pros: Very well Constructed
Professional Level
Easy to terminate
Very Cost effective

I have been in the Business Phone/Communications Industry since 1981. I have used many many different Brands through out these years. And I am very Happy to say that these are as good or better the then Top brands in the trade, ie ICC, AllenTel, DynaCom and Lucent.

I will be back for more and you are now my supply house for this and more.

Good product

Pros: Easy to work with. Hardly needing special tools

Cons: it is very wide

If you are to install it in 1-gang wall plate, there is no issue. If you are to install it with multiple hole plate, you need to pay attention as it may block the hole next to it.

Broke on first punchdown

Pros: Price

Cons: Cheap

It is poorly constructed. The gap to place a wire in to punch it down was non-existent. I gently opened the gap with a small screwdriver, placed the wire into the gap to punch it down (proper punchdown tool, set to low) and the plastic broke. I have experience with punchdown tools and this was not user error.

Hello Tim,

Thank you for your review and truly sorry to hear about the issues experienced with PID 7296. Just to verify, was this an issue with both keystones on this order? Unfortunately, it appears as though you may have received a defective keystone. If you would like, I can help setup an RMA for a replacement. Obtaining a replacement would be of no additional cost to you. If you wanted to proceed with the RMA, please let me know and I can get that started right away. Apologies again for any inconvenience and hope this helps!

Great for the price...but

Pros: Price

Cons: Cannot be used with plates from another manufacturer. The back side of the jack is quite bigger than normal.

They seem to work great. But I found that if you try to use a two outlet plate from another manufacturer with the holes vertically, they don't fit correctly due to the size of the backside where the punch down terminals are. The height of the terminal block is just a few millimeters too tall and will not let the jack above fit correctly in the slot. I found this out when someone stepped on the Monoprice plate and broke it. So I could finish the project, I had to purchase another one and found this out. Otherwise ok. Again, this is with another manufacturers plate. It is not all standard as I thought. No problem. Just a glitch. Otherwise great.
