Ideal where an external device must be kept operating for a lapse of time dependent on the paid amount. For instance: cleaning washing drying systems in service stations, campsites and swimming pools; spotlight plants in museums and tourist sites; tanning lamps in beauty-centers; internet cafés, and so on. The Time-box units are available in two sizes, Timebox B (large, with display, 650 coins cash-box) and Timebox S (compact, 250 coins cash-box), each of them in grey or black. The unit is contained in a solid 2 mm thick sheet case. The cylinder lock grips onto 3 locking spots, thereby offering strong resistance to efforts to break into.
