Ninety-degree Cat 5e keystones route the cable at a right angle to the insert, which can help when cable approaches from the side or installation depth is limited. One-hundred-eighty-degree keystones keep the cable path more in line with the insert, and both styles support RJ45 UTP terminations with 568A or 568B wiring, so choose the orientation that fits the cable path and mounting hardware.

Cat 5e keystones fit many standard keystone-compatible wall plates and patch panels, including plates from multiple manufacturers. Check the specific mounting strap before installation, because compatibility can vary, and some three- and six-port straps may not support these inserts.

T568A and T568B use the same four twisted pairs but assign the orange and green pairs to different pin positions on a Cat 5e keystone. Both provide the same network performance when the wiring standard matches at each end, so choose the pattern that aligns with the existing installation and use it consistently.

Color-coded Cat 5e keystones let installers assign different colors to phone, data, and Power over Ethernet (PoE) connections for faster visual identification. This organization can simplify labeling, troubleshooting, and future maintenance in structured wiring installations.
