Keystone floor box insert LOGILINK NK4070 for 12 LC-Duplex or 12 SC-Simplex adapters

LOGILINK NK4070 is a keystone floor box insert designed to house up to 12 fiber optic adapters in a compact modular frame. The insert accepts either LC-Duplex or SC-Simplex adapter types, enabling organized termination of multimode or singlemode fiber connections inside floor-mounted outlet boxes. The low-profile insert is intended for professional environments such as offices, data centers and AV installations where neat cable routing and reliable patching are required.

Advantages

The NK4070 provides a standardized mounting format that simplifies installation and maintenance of fiber terminations in floor boxes. Its modular design lets technicians choose between LC-Duplex and SC-Simplex adapters without changing the insert, supporting flexible cabling layouts. The unit contributes to clear fiber management by grouping up to 12 adapters in a single plate, reducing clutter and making labeling and access more straightforward.

Suitable for

• Office floor outlets requiring fiber termination and tidy cable routing
• Data center peripheral or access-point locations where compact adapter density is needed
• AV installations and meeting rooms with concealed floor connectivity
• Retrofit projects where a modular keystone solution simplifies upgrades

When it may not be suitable

The NK4070 is intended specifically for mounting inside compatible floor outlet boxes and for use with LC-Duplex or SC-Simplex adapters; it is not a standalone patching panel or enclosure. If your installation requires bulkhead adapters of other form factors, angled adapters only, or higher-density fiber counts beyond 12 adapters per insert, a different product may be more appropriate.

Key specifications

• Adapter capacity: up to 12 fiber optic adapters
• Supported adapter types: LC-Duplex or SC-Simplex
• Intended fiber types: multimode and singlemode compatible (adapter dependent)
• Mounting: keystone-style insert for floor outlet boxes
• Finish/color: black

How to use

Install the NK4070 into a compatible floor-mounted outlet box following the box manufacturer’s mounting instructions. Choose the required adapter type (LC-Duplex or SC-Simplex), install adapters into the insert until secured, and then terminate or patch the incoming fiber pigtails or jumpers to the installed adapters. Arrange and secure fiber slack inside the floor box to maintain bend radius and protect connections; label each adapter location as needed for identification.

What to consider before purchase

• Verify that your floor outlet box accepts keystone-style inserts of this size and format
• Confirm whether you need LC-Duplex or SC-Simplex adapters and that adapters are ordered separately if not included
• Check fiber type (singlemode or multimode) and connector polish/angle requirements for compatibility
• Ensure adequate internal space in the floor box for fiber routing and strain relief

Usage recommendations

Maintain minimum bend radii for fiber cables when routing inside the floor box, secure fibers to prevent movement, and use clear labeling on each adapter to simplify future changes. For long-term performance, use dust caps on unused adapters and verify end-face cleanliness before making connections.
