This distinctionis not always clear even tothose who are somewhatfamiliar with the subject ofbuilders hardware; but avery simple way to remember which is right and which left,is to bear in mind that when a door, in opening, turns on itshinges in the same direction as is followed by the hands of aclock, it is a right-hand door, and contrarywise a left-handdoor.

The better class of butts are,accordingly, made with .a loose pin, Figure 85, which can bereadily withdrawn if the door is to be unhinged. A fast-pinbutt would have exactly the same appearance as this when puttogether. Figure 86 is a third variety, known as a loose-jointbutt. In this the pin is cast or attached solidly to the lowerhub, working in the hollow hub of the other leaf, as shown bythe dotted lines of the figure. This form permits the doorto
