Protect and organize fiber splices
Dome, inline, aerial, and underground closures.
Sealed enclosures for joining, branching, and repairing fiber — matched to aerial, buried, wall, and manhole locations.
Closures and accessories
Vertical, horizontal, aerial, underground, and wall-mount options with splice trays.
Dome (vertical) closures
Cable entries at the base, common for aerial and underground use.
Inline (horizontal) closures
Cables enter from both ends, suited to straight-through joins.
Aerial closures
Designed for mounting on poles or strands.
Underground and direct-buried
Sealed for manholes, handholes, and buried routes.
Wall-mount closures
For buildings and indoor risers.
Splice trays and accessories
Trays, sleeves, seals, and mounting hardware.
Why sealed closures protect the network.
They keep moisture and stress away from splices and keep fibers organized for future work.
of this product range
Moisture protection
Protects splices from water and contamination.
Organized fibers
Fibers can be found and serviced later.
Clean joins and branches
Cables can be joined, branched, and repaired cleanly.
Re-enterable designs
Allow future additions when needed.
Longer network life
Extends the life of the fiber network.

Match to equipment and site.
Cable size
Closure entry ports must suit the diameter of the cables used.
Fiber count
Choose splice tray capacity for the fiber count.
Cable type
ADSS, Figure-8, and underground cables each need compatible entry and sealing.
Location
Aerial, buried, wall, and manhole locations call for different closures.
Splicing
Fusion splicing uses splice protection sleeves held in the trays.
Decisions that get the choice right.
Capacity
Allow for future splices and branches.
Environment
Match sealing and mounting to where it will sit.
Re-enterability
Choose re-enterable designs if the closure will be opened again.
Cable entry
Confirm port count and cable diameter range.
Common questions
Why can't splices just be left exposed?
Moisture and physical stress degrade splices over time and cause faults.
Can a closure be reopened later?
Re-enterable models can be opened to add or repair splices and then resealed.
Does one closure suit every cable?
No. Entry ports and capacity must suit the cables used.
