Ideal Security SK3015 Door Closer with Torsion Bar, 10-1/2 in L

Ideal Security's Extra-heavy-duty pneumatic (air pressure) door closer for 1-1/2 in Thick heavy, out-swinging aluminum, steel or wood storm doors. The flat torsion bar on the closer will flex and be under pressure, aiding in the latching of heavier doors. The door closing speed is adjustable with the air adjustment screw. The tube is aluminum, which will not rust. A speed release washer is included for easy closing when used to hold the door open: A simple push on the door will release the washer and allow the door to close. To protect your door and door closer from damage, we recommend adding a storm chain (SK14). Easy to install, using the existing holes on your door. The closer can be installed at the top, middle or bottom of your door, depending on its construction. Brackets and screws for installation are included.
