RIXSON's new Light Duty Pivot Series helps bring high-end door control to lightweight, narrow and low-frequency doors. Model 173, for offset applications, and Model 176 for center-hung doors, offer a concrete anchor for a sleek installation. There are no floor plates or no visible attachment to detract from the beauty of the door opening. The top pivot acts as a guide for the swing of the door and maintains alignment, while the bottom pivot bears the weight of the door. Information: www.rixson.com.
