Fetterlock: this, so far as heraldic drawing is concerned, appears to be the same as what is elsewhere blazoned as shacklebolt, shackbolt, or manacle. It is, in fact, a 'handcuff,' or prisoners' bolt, and generally represented as shewn in the margin, though sometimes represented of a square form. In the arms of SHAKERLY, Worcestershire, they are sometimes represented more like oval rings, while in the crest of WYNDHAM the semicircular part is generally represented as a chain, and in the badge of PERCY it is made to resemble the swivel, as in the arms of the IRONMONGERS. A double bolt also occurs in the arms of ANDERTON.
The device does not seem to occur in the more ancient rolls, but it is found very widely spread among several ancient families.
