Knollan develops and manufactures innovative combination locks composed of a small joystick pad and a durable plastic construction.

Whereas conventional combination locks utilize a dial for inputing the code, Knollan locks allow users to unlock the device with a four-directional slide mechanism.

Benefits of this patented technology include speed, ease of use in the dark, and one-handed operation.The company offers the SALY Dance padlock and SALY Wheel integrated bike chain lock.

Both devices are equipped with the same type of locking mechanism.
