Cyro'd Outlets - Need strong hold on Elrods


I bought a pair of cryo'd outlets, but they will not keep a tight and secure hold on my new Elrod Sig 3 power cables.

Does anyone know of a cryo'd outlet that provides an extremely good "hold" on heavy power cables like the Elrod?

Dan, are you saying that the Acme I bought from you grips better than the Wattgate?
Thanks to all of you....(except the devilish angelic pin-headed response) to my question.
Dear Psychicanimal, Absolutely, they do have a high bite rate, but please let me clarify. The Wattgate has a very high grip rate as well as improved contact surface area with quality triple plating for outstanding a/c transmission. However, the P&S (Acme) will "bite" as if it has teeth (to the point it can distort the surface of the blades). It seems like he is having trouble falling out (don't we all) and this can be the answer to his problem. I am not placing the P&S (Acme) above the Wattgate outlet. But they do tend to "snag" the plug blades to help with his issue. Sorry for any misunderstandings and I hope this helps clarify my explanation.
