The R3-Joint (Rope-Reinforced Rubber - Joint) mast foot rubber joint from S4LT has an aramid safety line (Kevlar) that runs through the core. The breaking load of the aramid tendon is approx. 200 kg.
The R3 joint has an M10 and M8 thread. The dimensions correspond to those of the rubber joints previously available on the market. The R3 joint is therefore compatible with previous systems and is installed as standard in the S4LT 211 Base.
M10 / M8
(An M10 / M10 version is being planned and is expected to be available from January)
The 211 Base only works with an R3 joint M10 / M8 rubber joint! Conventional rubber joints do not work due to the lack of screw holes on the head of the rubber joint.
