Review: There are several different ways these door knobs can be used. When I worked out which way suited my application DIY installation was easy, providing you have the right tools. The quality of the parts seems to be high and should last along time. There is a nice positive feel to the tension of the spring mechanism. The antique brass finish looks great on my light oak doors and though not cheap I think they are excellent value for money.
