Review on ICC CAT5E RJ45 Keystone Jack For EZ Style Office Electronics by Michael Heidelberg

I've been a telecom installer for many years and these connectors (stacked, not side by side) literally double my productivity in bulk installations. I recently did a 120+ seat job and had to do it with traditional square keystones - it took twice as long as a previous job where I used these bushings instead. These jacks are expensive but save you more time/labor than you make up for. You will never return to the square capstone. One caveat: some 4-port and 6-port wallplates have keystones very close together. You can't mount these connectors side by side on those crushed wall panels. I've only encountered this problem when using cheap Amazon wall panels or Chinese no-name manufacturers. If you are using Leviton or ICC slabs, the trapezoid stones are spaced far enough apart for these connectors to fit perfectly.
