Automatic door closers, such as those made by Briton, are used at many types of businesses, such as restaurants and retail stores. An automatic door closer ensures that a door shuts completely. You can install a Briton automatic door closer on a door in your home or business.
Remove the closer unit from the back plate with the socket wrench. Place the back plate along the top edge of the door, and make a mark for the bolt holes with the pencil.
Drill holes, for the bolts, on the marks you made in Step 1 using the power drill. Place the back plate at the top edge of the door, and secure it with the bolts using the socket wrench. Insert the bolts into the holes, and tighten the nuts to the bolts.
Connect the end of the tension spring to the upper peg on the closer unit. The end of the spring should go into the groove. Push on the claw to make sure there is a smooth return of the mechanism.
Attach the arm bracket assembly to the head frame of the door with the power drill. Place the closer unit back on the back plate, and secure it with the socket wrench.
Secure the junction box to the door jamb with screws using the power drill. Attach the 90-degree elbow of the box plug to the angle bracket on the back plate.
Connect the electrical wires to the terminals for the electro magnet, and then connect the electrical wires in the junction box. Twist together the black wires and cover them with a wire cover. Twist the white wires together and cover them with a wire cover. Attach the green ground wire to the ground screw using the screwdriver.
Insert the arm into the spindle, and secure the secondary arm to the face of the door with the power drill.
You can set the arm on the control unit to hold the door open or to have it set to "free swing."
