Unifix Universal Stainless Steel Wall Starter

The Unifix Wall Starter System is the ideal way to join new masonry to existing walls. It comprises a corrosion resistant stainless channel which is screwed to the existing wall using the plugs and coachscrews supplied, and a stainless steel sliding wall tie which will accommodate any common size or type of masonry. It will resist a wind load of 4.5 kN over 2400mm. Each pack contains all the necessary fixings to construct a single skin of masonry 2400mm high.


Categories: ,
  • Internal and external use
  • Brickwork, blockwork and random stone
  • Single leaf or cavity wall
  • Masonry up to 8 metres high
  • Wall widths from 60mm to 250mm
  • Imperial and metric masonry
  1. Prepare existing walls by removing any rendered or pebble dashed finish.
  2. Offer the lower section of the wall connector channel to the existing wall at the centre point of the new masonry.
  3. Plumb the lower connector channel marking the position of the fixing holes which should be equally spaced to avoid mortar joints. Then drill and plug the existing masonry.
  4. Lightly clamp the lower section at the 2 lower fixing points using the coach screws and washers provided.
  5. Slot the upper section of the wall connector channel into the lower section. Then drill and plug the remaining fixing points into the existing masonry.
  6. Lightly clamp the upper section at the 2 upper fixing points and the 1 overlap fixing point using the coach screws and washers provided.
  7. Align both connectors and tighten all coach screws (do not over tighten).
  8. Lay brick or block work for the new wall in the conventional way leaving a full vertical mortar joint between the new and existing walls.
  9. Install wall starter ties into the wall starter channel by twisting and sliding into position at 300mm centres. The ties should be completely surrounded with mortar.


Please Note

• In cavity wall construction, each leaf requires a wall connector kit.

• For external walls proceed as per fixing instructions but ensure the bottom edge of the wall connector channel is above the damp proof course. The vertical joint between the existing wall and the new walls must be weather sealed.
