The "cone" retainer is a protective retainer that, when used in conjunction with the tube, protects the formwork elements from concrete entering the tube.
The "cone" retainer is installed on the PVC tube, increasing the area of contact with the formwork shield. The retainer is installed at the ends of the tube.

The role of the tube is to form a through hole in the mass of the poured concrete for the screed bolt of the formwork. The function of the "cone" retainer is to prevent concrete from getting inside the tube. After removing the formwork, the cone nozzle can be reused. The "cone" type retainer is a plug designed for coupling screws. The inner diameter of the "cone" retainer is 22 mm, ideal for PVC pipes and PPE pipes.

An indispensable condition for the construction of the formwork is the installation of tie screws. The main function of the "cone" retainer is to overlap the holes of the protective tubes in which the coupling screws are installed. The coupling screws must be isolated from contact with the concrete mixture, otherwise their dismantling will be impossible later. Strong plastic is used for the manufacture of fixators. The quality of such plastic is due to the fact that it easily takes a given shape and is not subject to corrosion. A significant advantage over other consumables is that the "cone" retainer can be reused after removing the formwork.

If you try to save on the retainer, you can lose the coupling screw when dismantling the formwork, the cost of which significantly exceeds the cost of the retainer.

The main properties of the "cone" retainer are that it is resistant to high and low temperatures, as well as to changes in their values, is not afraid of the influence of external factors, does not deform over time, is made of high-quality material, prevents concrete from flowing into the tube, protects against ingress. concrete on the coupling screw.
