WM055-06 LDWB – Large Distribution Wall Box

Features and Benefits
• For internal or external use.
• Can be supplied with single element or single circuit trays. Single element
splice capacity is 240 fibres. Single Circuit splice capacity is 160 fibres.
Single circuit splice trays are a single tray with two separate storage areas.
• Note: For use with 1.5mm splice protectors. Crimp splices can also be used
in the single element trays but the capacity is reduced to 6 fibres per tray.
• Each box comes supplied with a top and bottom routing manifold for fibre
routing to the splice trays.
• All fibres are positively managed to maintain a 30mm minimum bend radius
within the wall box.
• Splice trays hinge upwards individually, allowing full access to spliced fibres
without disturbance to live fibres in adjacent trays.
• The box can be adapted for multiple applications using a variety of kits for
loop cable entry, in-line cable entry, locking for aerial cables etc. See
additional items on pages 3 and 4.
• The box is suitable for loop and riser applications.
• Cables can enter / exit from the top or bottom face of the box.
• The box is sealed to IP55 and the boxes are moulded from UV stable material
to prevent discolouring. The boxes are made using flame retardant UL94-V0
rated materials
