Optical fiber splice closure electro base Mini-Closure-4F, for 4 fibers, dimensions 160×45×14 mm

Optical fiber splice closure electro base Mini-Closure-4F is a compact enclosure designed to house and protect up to four optical fiber splices. With external dimensions of 160×45×14 mm, the Mini-Closure-4F provides a low-profile sealed environment that helps prevent moisture ingress and mechanical damage to fiber splices. The unit is suitable for indoor locations or protected outdoor installations where space is limited and a discrete splice point is required.

Advantages

The Mini-Closure-4F offers a small footprint and lightweight construction that simplifies placement in constrained spaces. Its sealed design reduces the risk of moisture and dust affecting splice integrity, while the internal layout facilitates neat organization of splices and short buffer tubes. The closure's robust housing provides basic mechanical protection and stable environmental resistance appropriate for protected mounting conditions.

Suitable for (tasks / use cases)

• Organizing and protecting up to four optical fiber splices in building distribution closets
• Wall- or panel-mounted splice points in indoor enterprise or telecom environments
• Small outdoor locations with shelter or protected cabinets where low profile enclosures are required
• Temporary or permanent fiber maintenance points for short fiber runs

Key specifications

• Capacity: up to 4 fiber splices
• External dimensions: 160 × 45 × 14 mm
• Enclosure type: sealed compact splice closure
• Protection: moisture and dust resistant for protected installations
• Mounting: suitable for wall, panel, or sheltered outdoor mounting
• Internal organization: provisions for neat arrangement of splices and short buffer tubes

How to use

Prepare fiber ends according to standard splicing procedures and install heat-shrink or mechanical splice protectors on each splice. Open the Mini-Closure-4F housing, place the prepared splices inside the internal compartment and secure them to the provided retention points or splice holders. Route incoming and outgoing fiber cables through the designated entry points and ensure cable seals or grommets are correctly positioned to maintain the enclosure's protective properties. Close the housing and verify that the closure is seated and sealed to prevent ingress of dust or moisture.

Usage recommendations

Use the Mini-Closure-4F in applications where a compact, low-profile splice point is needed; avoid exposing the unit to direct, unprotected outdoor conditions. Follow standard fiber-handling and splicing practices, ensure proper strain relief on incoming cables, and install the closure within sheltered or climate-controlled enclosures when long-term outdoor exposure is possible.
