Rigid plastic tubes with smooth or rough surface. Plastic tube is easy to cut to the required length. Used as a distance spacer in the formwork or as a sleeve over tie bolts. To save the formwork we advise the use of cones.

Supplied in 2 meter lengths.

Rigid plastic tube with star-like profile. The outside ribs of the tube gives a higher buckling resistance.

Supplied in lengths of 2 meters.

Cones are used on both ends of the tie rods sleeves to increase the supporting surface at the formwork. Easy extraction of the cones after the removal of the formwork. Cones form a chamfered recess in the concrete for easy grouting. Available in a wide range of recess depths and for different sleeve diameters.

Conical plastic plugs to close sleeves or holes in formwork or concrete parts.

Cap in concrete grey colour used to produce the assembled version of the Opti Wall Spacers. The Opti system is tested for waterproof. Opti Caps are closed with Opti Stoppers.

Elastic stopper to seal the inside of the sleeves against incoming water and as a backing where grouting is necessary.

Plastic coupler to connect plastic or concrete tubes.
