• - For use without waler or counter plates in both timber and steel formwork.
• - Zinc plated
• - h= 55 mm
• - s= 27 mm.

Galvanized Counter Plates / Plain

• - Counter plates made from steel ST 37.
• - To accommodate tie rods DG 15/17.
• - To be used in both timber and steel formwork with wing or hexagon nuts.
• - Hot-dip galvan

Hexagon Nuts / SW 30

• - For use with tie rods DG 15/17 in both timber and steel formwork with waler or counter plate.
• - 50 mm length to be used also as bar connector.
• - To be operated by means of a spanner.

Water Stoppers or Barriers / SW 36

This malleable cast iron - Grade BM 30- 06 Grey iron part is used together with tie rods DG 15/17 for the construction of watertight concrete walls. It is very often the case that customers demand the tie rods to be connected up to a so-called waterstop in the middle of the wall.

• - Zinc plated.
• - Hex size s= 36 mm

These systems are used for basement walls or tanks where a watertight structure is required. After the concrete has cured the bars are unscrewed from the watertight coupling, formwork cones removed and the holes are then grouted with mortar or injected with polyester resin.
