<p>The adjustable-height rowlock pin is for recreational rowing boats, its lower part being in the form of a screwed bar, fitted in a tapped hole in the mounting. Thus height can be adjusted by screwing up or down, and held by means of a locknut. Height adjustment can be by handwheel or handle, and the locknut can likewise be secured and released by a handle, so that no tools are necessary.</p> |
