Pros & Cons
👍 Pros
- 110-type IDC termination at 90 degrees is the industry standard connection method, ensuring a reliable, gas-tight conductor seat that maintains Cat6 signal integrity.
- Wiring diagram is printed directly on the jack body — T568A and T568B reference is always present at the point of termination, reducing punch-down errors in the field.
- Cat6-rated construction ensures this jack doesn't become the channel bottleneck in 1 Gbps installations and supports 10 Gbps over shorter runs.
- Standard keystone snap-in form factor is compatible with virtually any keystone wall plate or patch panel without adapters.
- Black finish provides a clean, neutral appearance in both residential and commercial installations.
👎 Cons
- Width of the keystone body prevents two units from being placed side-by-side in a single wall plate — a real constraint when planning high-density multi-port installations in a small footprint.
- Punch-down tool is not included — a 110-blade punch-down tool is required for proper termination and must be sourced separately.
- No color options beyond black noted in the product listing — installations requiring color-coded port identification need external labels or different keystone sourcing.
Frequently Asked Questions
What wiring standard does the LP985 Monoprice Cat6 jack support — T568A or T568B?
The jack includes a wiring diagram printed directly next to the wire clips, showing both T568A and T568B configurations. This means you can terminate to whichever standard your installation uses without referencing an external guide. Consistent standard selection across all jacks in a run is critical for link integrity, so the on-jack diagram reduces punch-down wiring errors.
What connection type does this keystone jack use, and what tool does it require?
The jack uses 110-type IDC (Insulation Displacement Connector) termination at a 90-degree angle. You'll need a punch-down tool (not included) — a 110-blade punch-down tool is standard for this type of termination. A quality punch-down tool seats the conductor cleanly and trims the excess wire simultaneously, which is important for maintaining Cat6-grade signal integrity at the termination point.
Can two of these keystones be installed side-by-side in the same wall plate opening?
No — the manufacturer explicitly notes that the width of these RJ45 keystones prevents two from being used side-by-side in the same single-port wall plate opening. Plan your wall plate layout to use multi-port keystone plates with adequate spacing between ports, or factor this into your panel density planning.
What network speeds does Cat6 support through this jack?
Cat6 is rated for 1 Gbps up to 100 meters and can support 10 Gbps up to approximately 37–55 meters under ideal conditions. The keystone jack must be the correct grade to avoid becoming the weakest link in the channel — this jack is Cat6 rated to maintain that specification at the termination point.
Is this keystone compatible with standard keystone wall plates and patch panels?
Yes — the 110 IDC, 90-degree form factor is the standard keystone snap-in geometry used by virtually all keystone-compatible wall plates and patch panels. It mounts with a snap-in fit into any standard keystone slot.
