Product Description

31-Set  Pair of Plate, Cup & Connector - The 31S rigging screw snaps into this plate which is set in the deck.

These come with either moulded glass/epoxy "cups" for IOM or in carbon/epoxy "cups" for other classes, please specify in message box when checking out.

This is a set of parts that can be retro-fitted to an existing or new boat that will enable the snap in/out rigging screws (item 31s) to be used.

These rigging screws have a ball at the lower end that engages positively in a keyhole plate recessed into the deck. A compression spring lock provides added security to prevent the rigging screw coming out when the shroud goes slack. The snap in/out rigging screw is quick to attach when rigging the boat, can be adjusted in situ, leaves no exposed hook that will foul rigging lines on board or another boat’s rigging, and does not foul other items of rigging when in transit. The plate, cup and connector system enables the system to be installed in most boats.

The cup is a moulded glass/epoxy or carbon/epoxy ‘cup’ shaped part that provide a shallow 13 mm watertight recess in the deck. The plate is a 15 mm diameter stainless steel plate with a keyhole cut out that the rigging screw engages into. Two holes provided for M2 screws to be used to fix the plate down through the cup to the connector. The connector is a T shaped piece of stainless steel. Two tapped holes take the M2 screws that hold the plate down. The leg of the T is used to connect to the diagonal strut that takes the load of the shroud to the keel/floor of hull. We use TubeJ for this purpose but any suitable 6 mm ID tube will do.

If the cup should get sand or dirt into it such that the ball of the rigging screw cannot be inserted, do the following to clear it. Remove ONE of the M2 screws holding the plate. Slacken the other until the plate can be raised enough to rotate it 180 degrees. Clean out the debris, place the plate back in position and replace the screws.
