British General IP55 Enclosure Grey 270 x 180 x 135mm (86625)

Hi RogerIW, This is a weatherproof enclosure intended as a junction box or to contain any items which need to be outside but protected from weather, by completely surrounding the connection or item. Where there is an existing socket enclosure it is unlikely that this box will fit over it as the back section would need to be under / behind the existing wall box in order to ensure the box is correctly sealed against fluid once the lid is screwed on.

Hi, thank you for your product enquiry. The lid of this British General IP55 Enclosure Grey 270 x 180 x 135mm is gently curved (for stability/rigidity) as can be seen best in the second image.

Hi, thank you for your product enquiry. This IP55 Enclosure Grey 270 x 180 x 135mm is suitable for permanent installation outside as long as all knocked-out cable entries are suitably glanded and the cover is fitted correctly.

Hi, thank you for your product enquiry. A 20mm cutter is a drill attachment for cutting 20mm diameter circular holes easily, but your solution of a Stanley knife is equally appropriate where a hole cutter is not available.

Hi, thank you for your product enquiry. This IP55 Weatherproof Enclosure does not come with any glands or seals as the appropriate gland or seal will depend on the cable size and type being used.
