Universal layout hard hull chock made of mirror-polished AISI 316L stainless steel. The bottom of the chock can be built-in to the deck by a fast removable base or fixed without recess; a double arch bracket is connected to a base and is covered by a special surface to reduce friction and scratches on the hull. Thanks to its particular shape, this holder can virtually fit a multitude of hard hull designs such as tenders, watercraft or Jet Ski and can be adjusted with a simple movement, without having to move the installed bases. The extractable version is supplied with a special built-in holder (Art 2530). Payload 160 Kg.
