therein against rotation relative to plate 8. Plates 8 and 10
can be secured firmly together by fitting plate 10 so that
bolts 22 extend through holes 20 and applying nuts to the
bolts, the nuts being received in recesses 18. At their
confronting surfaces, plates 8 and 10 are each formed with
five grooves 40. Each groove is substantially horseshoe-shaped
when viewed in plan, and is semi-circular in cross-section.
The grooves in plate 10 register with the grooves in plate 8
when the two plates are secured together, so that passages 42
of circular cross-section are thereby formed.
Perry's peripheral anchor 4 comprises a flexible steel
cable 44 having a neoprene jacket. Cable 44 is formed with a
loop 46 at one end, a ferrule 48 being used to secure the
loop. The loop 46 is sized to fit in one of the passages 42.
At its opposite end, cable 44 is attached to a disc or plate
54. The disc 54 has a flat attachment surface. A hole is
drilled in disc 54 from its periphery. The neoprene jacket is
removed from the end of the cable so as to expose the twisted
strands of steel. Epoxy adhesive material is introduced into
