(HST-WA) Key Exchange Boxes

STAINLESS STEEL EXCHANGE BOXES

The HST-WA range of exchange boxes are used to increase the number of keys available in an interlocking sequence. The operating principle is such that no secondary keys can be removed from the unit until all primary keys have been inserted and trapped. The primary keys remain trapped until all secondary keys have been returned. HST-WA key exchange boxes are available in every possible combination of primary and secondary key numbers and are generally used for larger interlocking sequences. The lock portions are manufactured of stainless steel and supplied with protective dust caps as standard.
