Shop for Hardware at The Home Depot. The Ideal SK8730 for storm and heavier screen doors includes a heavy duty pneumatic (air filled) door closer, wind chain and a special wide base bracket for the door closer. This door closer is for out-swinging doors. The wide bracket allows for new holes to be made for extra strength in holding the door closer in place. The heavy duty closer features a winter and summer setting for when screens are used instead of glass and features an air by-pass for extra latching power. The storm chain is used to protect the door, the glass and the door closer pump from being damaged if a strong wind catches the door as it is opening. The SK8730 door closer is for storm and screen doors that are from 1-3/8 to 2 thick. The closing speed is regulated by a screw at the end of the tube. Tightening the screw will slow or stop the closing. If your door is a lighter weight you could use Ideal s SK9 door closer. The door closer in the SK8730 is the same as Ideal s SK1730 series of closers, except the SK8730 includes a storm chain and special wide base jamb bracket. All fasteners and brackets are included for a complete and easy installation. The wide base bracket is available without the door closer as the SK26. This door closer is original equipment quality. Ideal Security supplies storm door hardware to quality door manufactures across North America. The SK8730 is painted black. The storm chain is painted black. All screws are painted black. Door not included.
