Abstract
Abstract A coin telephone unit is provided with two covers -an inner strong intruder resistant cover and an outer lightweight cosmetically attractive cover. The inner cover can be painted an attention drawing colour. The inner cover does not need replacing if damaged during an attempt to remove it. The inner cover can be more easily and cheaply made as only strength and not appearance need be considered. Damage to or wear of the outer cover requires only replacing of relatively cheap outer cover.
