Double Interlock SM2T Touchscreen Lock for Steel Doors

An interlock lock is an auxiliary device that ensures that the doors of a cleanroom cannot be opened simultaneously, thus ensuring the isolation between the clean and non-clean areas.

The Double Interlock SM2T lock for steel doors is a high-quality product with features similar to a standard double interlock lock.

It has the capability to control the opening and closing of two door panels simultaneously. When door 1 opens, door 2 is forcibly closed, and door 2 can only be opened after door 1 has closed.
