The mooring shock-absorber Garelli, model "MOL", is made with spring on harmonic steel, hot-covered with "Rilsan", and with connection on stainless steel AISI 316.
In this way, the spring is protected against corrosion and against the sun rays, and it will have no breaking problems, because being in harmonic steel, you can close the spring completely, and than, when you will let it, the spring will keep the same initial length. The heads are made on quality "Nylon" and not on PVC, and for this reason, it will have no problems with the sun rays and with the salinity of the see.
The "Mol" Garelli allows a silent, lasting and safe mooring.
