Hey kid, chock that door!

“Hey kid, Chock that door!”


There are many different ideas on how to chock a door. These pictured above are a few that I have run across in the past. Now I am not going to say that one is better than another but I will picture a few and show what each is good for and the many different functions that each can perform. However the door is chocked, just remember the importance of doing so in order to control it and most importantly keep it from closing on your hose line or worse, delaying you and your crew if you would have to evacuate in a timely manor.


The masonry nail has only one function in which it can perform and is pictured above. The nail is placed head towards the jamb and point toward the door, pull door as if you were going to close it and the nail will stab into the door holding the nail in place and keeping the door open. Another advantage of the masonry nail is if you have many doors to control a hand full of these can easily be carried.



This door control devise is easily constructed with a wooden dowel and a bent over nail into the top of it. This devise is easily deployed and light- weight but does not keep the door open as wide as we would like.



This is the 1119 door chock. As you can see it has many functions and is easily constructed by threading a plant hook into the top and then wrapping it with electrical tape. The electrical tapes allows the wedge to get a better grip when used under the door and adds extra strength from splitting when used in the hinge. This wedge, when used in the hinge, holds the door almost all of the way open giving us maximum use of the doors opening. The 1119 wedge can also be used to control a garage door by inserting the hook in a hole in the track of the door as shown in the above picture.



“The standard wedge” I am not going to talk a lot about this guy. This is the most widely used in the fire service. It works good is light- weight and easily constructed. It can also be used in the hinge area but as soon as someone walks by and pushes on the door to open it, the wedge will fall out and now will let the close behind you.



This door control devise is one that I have constructed out of ½ inch poly plastic. This device works rather well under the door as well as in the hinge. The size of this thing makes it a little difficult to carry and to pull out of your pocket very quickly. It is fairly light- weight and holds the door open to a perfect 90 degree angle and because of the notch it does not fall out.



This one here is fairly common and works really well. It is constructed by welding a planter hook onto a piece of angle steel, one can also drill a hole in the center and insert an s-hook through the hole and crimp down the end that is through the angle. This is one of the heavier door control devises but is very effective and durable.


This is the Caro hinge hanger. This one is easily constructed with a wooden dowel and a nail hammered into the side then bent over. The Caro hinge hanger is very light- weight and just as effective but sometimes has the tendency to twist out of place when put under a heavy load such as encountered with a heavy duty pneumatic commercial door closer.


The Wichita wedge is a very easily constructed and also effective door control devise. The Wichita wedge is basically the standard wedge with a notch cut into it so it can set in the doors hinge. The only downfall of this wedge is when the door is pushed to the closed position this device tends to split and now the door will close behind you.
