signamax 4 Pair Termination Tool for MT-Series Keystone Jacks

Description is not clear as it shows in picture that it can handle side punched connectors but it only does the end punch style. Good quality, just wish it could do both.

The other key point is it come with a spare die

good

It doesn't match the keystone port and I would like to return it

I love this tool. I've done probably 200 or so terminations with it, and I can't imagine going back to a punchdown tool for keystone jacks. One of my local cabling suppliers carries Signamax keystones and they've been great as well -- I've done at least 500 and never had a bad one. I've seen some Legrand keystone jacks at Lowes or Home Depot that were identical, so you should be able to use this tool with those as well.
