Method of attachment of door and frame to pre-fixed box allows for some degree of adjustment. Meter board and earthing stud fitted to box as standard. Cable entry holes fitted with blind grommets to allow choice of positioning.

All boxes fitted with slam lock and supplied with easy-to-handle triangular plastic key. Available in ESI Small, Medium and Large sizes.
