Review on Universal Keystone Punch Down Tool For Cat6, Cat5E, RJ11 And RJ12 Jacks By IMBAPrice by Alan Pfeiffer

This keystone jack holder is perfect for anyone terminating Ethernet cables. It ensures that the keystone connector/jack does not move, and more importantly aids the user in preventing injury. An example of this is terminating a keystone connector on a desk where it can slip and slide, or can cause discomfort in the palm when holding the keystone connector in the hand and terminating. Supports every make and style of keystone connector I have encountered so far.
