Selden 508-262-01 Gooseneck Assembly Complete - Fits Selden letter mast sections.

All new Seldén dinghy masts are fitted with our new gooseneck. Designed to reduce weight and increase strength and functionality, the new system features a round pin, to allow the boom to rotate in the direction of the load. The new pin is longer and features a unique gooseneck lock system to give it a positive engagement onto the boom. By clicking into place, the boom is
prevented from falling off the gooseneck when dropping the mainsail, saving injury to yourself and damage to the deck. It is also very useful when using a boom-up cover.

The vertical hole fixing spacing is 43.5mm
