Great Product

Great product. Perfect packaging, High quality material.

Great easy to use connectors

I used these on 2 tv's to extend the cables and they worked great.

Nicholas Sheehan
Manager did a great follow up

I had some problems reaching the tv from the wall plug. The Manager sent me the splicers and they function as they should. Thanks

High Quality Splice (male-to-male)

These are a great quality splice. I have had no issue with this product! They have little to no signal degradation passthrough from what I can tell. They are a quality connector, and making splicing two cables together a breeze.

My only wish, is they included in the packaging, or ChannelMaster had the option to purchase the accompanying jam nut, to secure these through a wall-plate blank. No stars lost, though as this was clearly not advertised.

Splice Adapter

This adapter worked great. Couples 2 cables & provides a great TV signal. Very well made- easy to screw cables on. Would definitely but again.
