The Sleeve2 is the only door security device tested under the pressure of an actual active shooter event. Fighting Chance Solutions’ classroom door lockdown device, The Sleeve, is utilized and trusted for door security by thousands of schools and universities nationwide.

The Sleeve2 overcomes the challenge of securing outward-swinging classroom doors in a matter of seconds. No modifications to the door, door frame, or building structure needed. Schools and commercial buildings in all 50 states use The Sleeve2. Many states have added the product to their approved lockdown door stops list.

Measuring The Sleeve²

The Sleeve2 is offered in twelve (12) sizes. It is designed to accommodate both surface mounted regular arm top jamb mounted and parallel arm door closers. These are the most common type of closers found on outward opening or push side doors.

Available sizes: 2.25”, 2.5”, 2.75”, 3”, 3.25”, 3.5”, 3.75”, 4”, 4.25”, 4.5”, 4.75” and 5 inches.

STEP 1: Locate your door closer

Door closers are located on the upper corner, hinged side of an outward opening door (the “push side” of the door).

Locate your door closer

STEP 2: Measure your closer


With the door closed, measure the distance between points A & B as illustrated below. Measure from the door side of the arm (point A) near the bend (or within 1⁄2 inch of bend) to the room side of the second arm (point B), or any other obstruction that would impede the Sleeve from sitting properly. This measurement should be taken perpendicular to the door.

For the most accurate measurement possible, make sure your tape measure is perpendicular to the door when you take this measurement.

**On this measurement we recommend that if you are between two measurements (ex. 3 1/4” or 3 1/2” choose the 3 1/4” ) choose the smaller measurement.

STEP 3: Select your Sleeve²

With the dimension obtained in Step 2 above, round down to the nearest 1⁄4 inch to determine the proper size of The Sleeve2 required for that door. You’re DONE!

E.g., measuring perpendicular to the door between the arms you obtain a measurement of 4-3/16 inches. Therefore, rounding down to nearest 1⁄4 inch you would select The Sleeve2 – 4.25 Inches.

*Note: the angle of closer arms even if they appear to all be common in a facility could vary due to substituted brands, installation or age. Before assuming all doors in a facility are common, you should always double check.

Deploying The Sleeve2 To Secure Your Classroom Door


In a crisis situation, seconds count in one place you don't want to be is in the hallway trying to lock your door and exposing yourself to a potential threat. This is why a fighting chance solutions created the sleeve. A 12 gauge carbon steel cover that slides over your door closer, securing your door from the inside. For a successful deployment of the sleeve, please follow these six steps. Step one, scan the room for the location of the sleeve, step to remove the sleeve and walk to the door. Step three, make sure your sleeve is right side up, so the open channel, the sleeve is facing the floor, and the this side, visible sticker is facing into the room. If you can't see the sticker or the words are upside down, readjust the sleeve. Step four, place the sleeve, the narrow end of the door closer again, making sure that the yellow label is facing into the room and his right side up. Step five, slide the sleeve on the closer arm as far as it will go. The sleeve should fit snug against the arms of the door closer. Step six, once the sleeve is on, move away from the door.


Recommended Deployment Practices 

  • The Sleeve can ONLY be used during active shooter situations, otherwise it is a violation of fire code.
  • The Sleeve should be secured and only accessible to trained and authorized individuals.
  • The Sleeve should never be used as a door locking device other than during an active shooter event.
  • The Sleeve should be removed from the door and secured as soon as the emergency event is over and an all clear order has been given, in accordance with emergency response procedures.

Sleeve FAQ

Does Purchasing or Storing The Sleeve Violate Fire Code?

The Sleeve is not a permanently mounted deadbolt, so the purchase or presence of The Sleeve is not a fire code violation. Deploying the device onto a door closer can be a fire code violation in some states, which is why life-threatening active shooter/violent intruder situations are the only time you may use The Sleeve. Many states have “approved” device lists posted for active shooter safety devices.

Do we need to make any installations or modifications to the door or any other parts of a building's structure?

No, The Sleeve is a metal cover that slides over the arm of a door closer. Most doors – especially those that comply with the Americans With Disabilities Act or are rated as “fire barriers” – will have an existing door closer. Because the product exists independently of the door and any of its hardware, the door or structure needs no modifications. That means no drilling, cutting, or installation of new hardware. In the case of doors rated as fire barriers, modifications are illegal, so The Sleeve would still work.

How durable is The Sleeve?

The Sleeve is made of solid, 12 gauge carbon steel (.104″ thick) that is folded into twelve sizes. The Sleeve is capable of withstanding more than 550 pounds of external force. Often a door closer will fail before The Sleeve does.

Can The Sleeve be removed quickly if an evacuation is necessary?

Yes, an advantage of The Sleeve is that it can be applied or removed in seconds. Several nationally recognized training programs instruct the use of cords and belts being tied in knots to secure a door. Not only is this ineffective, but it is also extremely time-consuming to apply and remove.

Where should we store The Sleeve?

How prominently The Sleeve is displayed in your room will be up to your district or building. You can purchase a hanger and mounting hardware to install at your discretion (look in the "Storage and Hardware section.") The screws are designed to work without the use of anchors on many surfaces including wood, drywall, metal, and brick/block. Hang The Sleeve near a door frame, or hide it near the door in a closet or drawer. It’s up to you.

Can I secure the door with The Sleeve if my door is unlocked?

Absolutely! As long as your door has a closer on the inside face. A benefit The Sleeve provides is that securing a door can be performed by anyone (substitute, building aide, or student), not just a person with a key to the door. Additionally, because the door is secure from the inside, the teacher does not have to risk being in the hallway during an active shooter situation. We always recommend that customers test the fit and securement of each Sleeve for each door to ensure proper functioning.

How long can I expect to receive my order?

We do our best to provided shipment of product 2-3 days after order placement. Most of the time we can ship the same or next day after order placement.

Why do you emphasize the importance of accurately measuring for your Sleeve?

The more accurate you are in gathering the requested measurement, the better The Sleeve will secure your door. We do offer free exchanges (you ship it back to us and then we ship you out a new size on our dime.) if you happen to measure incorrectly.

Could a student lock a teacher out of the classroom?

Unfortunately, there is always a potential for misuse. In our almost five years of existence (with tens of thousands of units sold) we have not had a reported case of misuse of The Sleeve. However, educating students and staff on the appropriate use of The Sleeve will be the best way to eliminate misuse. Educating students and faculty on how to use The Sleeve is as important as educating students on how to appropriately use fire alarms, fire extinguishers, and deadbolt locks.

Are all door closer arms the same?

No, door closers can be mounted and adjusted in several different ways. These differences are why we have created a simple one-step measuring process to find the correct Sleeve size to fit your needs.

Will The Sleeve work on doors without door closers?

No, it will not.
