Positional couplings Lentonr 13, 14, 15
Model R 13 couplings are designed for quick fusion of two curved, bent or straight rods, when none of the rods to be connected can rotate freely, while the rod is connected axially. Typically, such couplings are used to connect prefabricated frames. Positioning sleeve R 13 can be supplied in two parts for use in contact with formwork. The internal parallel thread is protected against corrosion by a plastic screw plug.
The model R14 coupling is similar to the model R13 coupling, except that the connecting rod in the R14 coupling can move freely in the axial direction. As a rule, such rods are used to connect pile frames.
Model R15 couplings are designed for quick connection of column sections or precision connection of elements with several rods that are connected to each other in a short section (for example, prefabricated elements), as well as for closing small temporary openings.
