Measuring the Sleeve

To secure a door properly, The Sleeve needs to fit snugly around your door closer. In order to achieve this snug fit, you must determine which Sleeve style you need (A,B,C, or D) and take four simple measurements with a tape measure or ruler. To show you how to select the proper style and determine these measurements correctly, we have included in the section below a number of different mediums to help you figure out The Sleeve that fits your needs.

Step 1: Decide What Model You Need By Locating Door Closer Position
Identify whether the door closer is a top left or top right mount on the door. Once you have identified the mount location, you must pick which of the models matches how the arms of the door closer are configured.

Step 2: Determine The Model For Chosen Mount
If it is a top left mount you will need model A or B, if a top right mount you will need a C or D. Reference the pictures below to assist you in identifying which model matches your door closer configurations. All views are shown looking down at the door closer from above. Notice how in model’s A and C the arm that is parallel to the door (going the same direction as the door) is closer to the surface of the door. In models B and D the parallel arm is further away from the surface of the door.

Step 3: Measuring Your Closer Arm
Measurement 1 is the length of the straight arm parallel to the door. Start the measurement at the outside edge of the pivot point and measure 1/2″ to 1″ before your first obstruction (bend or closer box).

Measurement 2 is for the opening of the sleeve so that it can slide on snug all the way to the end of measurement 1. Measure your opening from the outside edge of your straight arm to the outside edge of your angled arm at the point where measurement 1 was taken. For the most accurate measurement possible, make sure your tape measure is completely perpendicular to the door when you take this measurement and not at an angle. **On this measurement we recommend that if you are between two measurements (like 3 1/2″ or 3 5/8″ ) go with the smaller 3 1/2″.

Measurement 3 is the width of the pivot point. If your closer has a knob, you will need to measure from the outside edges of the knob.

Measurement 4 is the thickness of the two closer arms. This measurement is from the highest and lowest points of the closer arms. If a nut or knob adds thickness to the arms, then measure this thickness. It is critical that the thickness is correct to allow clearance for the Sleeve to slide on correctly.
