Pulllock / Toilet compartment door

Pulllock

It’s always a mess when you rush to the restroom but couldn’t find your place. How could you pick out a vacant one from those little stalls with absolutely the same appearance! It’s time for some changes. This pulllock provides you with clear direction that guides you to exactly the vacant one. If the stall can be used, it will show you with a reachable handle, or it just looks like unavailable.
