RFA-Tech plastic screed chairs are ideal for light duty applications. They are fully adjustable and being manufactured in plastic may be left in concrete, either in part or as a complete unit, without fear of corrosion. It is not advisable to use chairs in bays over 4 metres wide and we would recommend placement of 500mm centres. For heights over 150mm the base of the chair should be placed in a 'blob' of concrete for greater stability.
The plastic screed chairs are supplied in three parts: -
- Plastic Screed Chair Base
- Plastic Screed Chair Collar
- Plastic Screed Chair Saddle
