All initiating keys must be inserted into the type T interlock before the retained keys can be removed. After the retained keys are removed, the initiating keys are trapped in the interlock.

Type T interlocks are transfer blocks since there is no locking bolt projection through the base for locking any moving part.

Usually the need for a type T interlock can be eliminated by using multi-cylinder interlocks mounted on your respective devices, making it unnecessary to go through an additional transfer lock operation.

OPTIONS
• Key Removable - specify which key(s) is retained when remaining key(s) is removed.
• Multi-Cylinder - up to 15 cylinders available. Housings with 5 cylinders or more come with mounting holes at each end of the housing.
• Stamp Key Interchange - specify an alphanumeric code to be stamped on the cylinder face and the key (e.g. A1, A2, B1, etc). See Data Sheets 3.4 and 4.1 for details.
• Housing - Machined brass bar stock. Also available in stainless steel by special order - please contact Kirk Key for pricing and availability.
• Auxiliary Switches - Type K Switch | Type S Switches
• Dust Covers
• Mounting Bolts
• "Opposite Hand"

NOTE: When the number of keys in the transfer step exceeds 10, it may be advantageous to use a Transfer Panel instead of a Type T interlock.
