SS-KE Trapped Key Exchange System

The vertical key exchange system is required when multiple access points are present which need to be accessed at the same time. The SS-KE is available with 1 Key IN and up to 5 Keys OUT.

The keys used for the access locks are trapped until the control switch / isolation key is inserted. Only when the 1st key is turned and trapped, can you release the access keys (up to 5). The SS-KE allows for up to 5 keys to be released non-sequentially.

Due to the stainless steel construction, the SS-KE is suitable for use in harsh environments including struct washdown with corrosive chemicals up to IP69K.
