Collection: Adaptable Boxes

Browse Niglon galvanised adaptable boxes in a choice of square and rectangular sizes, from 75 × 75 × 50mm to 300 × 300 × 100mm. The boxes are made from pre-galvanised sheet steel and have screw-on lids, with selected depths of 50mm, 75mm and 100mm across the range.

Most models listed here include knockouts for cable entries. The 100 × 100 × 50mm box is supplied without knockouts, so check the individual listing before choosing. Black Niglon cord restraints for 10mm-entry lampholders are also listed separately and sold individually.

Select a box with sufficient space for the intended connections and cable routing. Check entry fittings, earthing requirements and the manufacturer's installation guidance; do not assume an outdoor or weatherproof rating unless specified for the model.
