Abstract: A carrier for supporting extended metal workpieces during electrolytic finishing treatments comprises a flight bar supporting at least two dependent spline members, both the flight bar and the spline members being electrically connected to the workpieces supported by the carrier. Each spline has two or more support arms for the workpieces and a clamp bar, carrying spaced clamp arms arranged at the same vertical interval as the support arms, is arranged for vertical movement in relation to each spline and is employed to clamp the workpiece in electrical contact with the upper or lower side of the adjacent support arm.

Abstract: A surface waterstop is in the form of a strip of rubber or plastics material. At least one keying formation, preferably a T-shaped formation, is provided on each side of a center line of the strip. A longitudinally-extending central section may be provided for receiving and locating stop-end shuttering. Along at least one lateral edge, and preferably along both lateral edges, the strip is adapted, for example by the provision of holes, slots or the like, to receive fixing pins or clips which, in use, extend at an acute angle to the surface on which the waterstop is laid.
