Reducing Classroom Distractions
I created DOOR BLOK back in 1988 after attending a study on classroom distractions. The presenter pointed out that the #1 distraction in the classroom was the sound of the door opening and closing. From the rattling of the knob or handle to the clunking of the door as it closed, these annoying sounds are heard a hundred times a day.
With a DOOR BLOK in place, it all goes away.
Normal Mode
DOOR BLOK makes it easy for students to enter or exit your room. Since the latch is not engaged, a simple push on the door will open it. The closing sound is muffled by the cushioning provided by DOOR BLOK's heavy-duty neoprene rubber.

Closed Mode
At the end of the day, DOOR BLOK will hang from the inside knob or handle. This makes it convenient to use as you'll always know where it is. There's no searching around or wasted time.

DOOR BLOK XL
For classroom doors that have latch guards or theft plates, use DOOR BLOK XL. The extra inch in length enables the DOOR BLOK to function normally.
